Gift shift problems in Mercruiser Inboard Engines

Written by boatplace

Problems with Mercruiser engine gear shift.

I started having trouble shifting in and out of gear with my Mercruiser 4.3 litre V6 engine and Alpha One stern drive. This was not a problem on the open water when uderway, but became a real nuisance when I was berthing the boat in a marina. Primarily because once in gear, I could not get the engine into neutral whilst the engine was running. There are a number of issues that can cause problems shifting gears and here are three potential causes of the problem.

  1. The gear shift cable. With continued use and ageing, the shift cable will deteriorate and begin to break down. The inner cable begins to fragment and then cannot move freely. There can also be problems if the cables are not lubricated. They need to be greased by your marine mechanic and checked to ensure they move freely.
  2. Gear shift bellows. These can leak and cause water intrusion which will also lead to problems shifting gears.
  3. Shift Interuppter Switch. Sometimes referred to as a micro switch or shift change switch. This device cuts the engine in a split second to allow the gear change without damaging your engine. These can deteriorate or break, making it difficult to neautralise the boat's engine.
My engine would go back into neautral when the ignition was turned off. This eliminated the shift cable, as it would still be stiff when the engine was turned off and if it were the problem. The gear shift bellows had recently been replaced, which eliminated them as being the cause. In the end, my marine mechanic isolated the shift interrupter switch as the root cause of the problem. A small roller had broken free rendering the switch unable to neautralise the stern drive.

Symptoms of a leaking stern drive on your boat.

Written by boatplace

Symptoms of a leaking stern drive on a boat.

The first sign my stern drive was leaking was the appearance of a milky substance in the small fill tank for the gear lube that sits on the top of the engine. At first it was a small amount at the bottom of the fill tank, mixed with the Mercruiser gear lube. But it was obvious. There were no other symptoms at this time, so I elected to monitor the issue and have it addressed during the next boating season's service.

A leak on a boat - even a small leak, can lead to a very big expensive repair bill. Although I was lucky this instance, I don't believe I was wise in waiting as long as I did. For what happened next illustrates that the condition of the stern drive gradually deteriorates at an accelerating rate as the leak becomes worse.

In the next couple of months and with continued use of the boat, I began to notice a more-than-normal amount of water building up in the bilge. As my boat has full bimini and rear sloping covers, minimal rain water can get into the bilge, especially as the drainage from the engine compartment is very good. My concern over the suspected leak increased, but I was not alarmed and continued using the boat.

Having drained and cleaned the bilge a few times, I began to monitor the engine bay after each use for signs of the leak. Immediately after I used the boat, I would venture into the confines of the engine bay and listen and watch for obvious signs of water intrusion into the hull. The drip-drip-dripping sound was evident although not immediately visible. I had to almost crawl under the engines to figure out which one was leaking and from where. 

When I did actually see the leak, I could see it was from the bottom of the main seal around the stern drive.  This is the very confirmation upon which I should have acted and that you need to know to act! The next symptom was a knocking sound which initially was not overly loud. However, with continued use of the boat the knocking sound intensifies. This is most likely the sound of your gimbal bearing under stress and working whilst full of sea water! There is also a strained 'growl' when the stern drive is steered hard to port or starboard.

At this stage I stopped using the boat and quite wisely, too. Further use could have caused immense damage that would have put me on hard stand for quite some time! I pulled the boat for its annual service and found that the u-joint bellows and drive seals had to be replaced. The gimbal bearing also needed replacement. There was no damage done to the gimbal housing or outdrive unit and I was lucky that this was the case.

These seals come in a kit and like most boat parts, seems excessively expensive. However, this kind of maintenance is not normally required annually, so you need to be aware of when the seals were last replaced. It's cheaper and easier to have them replaced prior to suffering a leak and risking damaging your engines. Peace of mind to have them done and keeping your stern drives happy for prolonged use of your baby!

 

Permanent Painted Coatings

 

POR-15 Fuel Preservative & Stabilizer Saves You

Time, Money and Worry

Permanent Painted Coatings is proud to announce the inclusion in its range of POR 15 Fuel Preservative and Stabilizer. Coming from the stable of POR 15 coatings products, this product is superior in quality and guarantees that your fuel will not oxidize in the fuel tank.

POR 15 Fuel Preservative and Stabilizer stops a breakdown process in fuel called oxidation. When a petroleum product stagnates for any long period (2 months or more), gums and varnishes are formed by the reaction of oxygen with the fuel. These by-products greatly reduce combustibility, octane value, and overall fuel efficiency. Furthermore, all internal fuel system passageways, lines, nozzles, valves, jets, etc. become restricted due to these gums and varnishes, which are very tough to remove once in place.

By adding POR-15 Fuel Preservative & Stabilizer to your tank, oxygen becomes chemically isolated, thus preventing oxidation. Additionally, powerful agents neutralize corrosive compounds and also prevent rust formation.

This product is safe for use in every type of fuel system and effectively preserves fuel for more than 2 years.

Benefits include:

  • Keeps fuel fresh for 2 years

  • Cleans fuel lines in concentrated doses

  • Stops corrosion and prevents gum & varnish formation

  • Quick starting

  • Elimination of fuel system overhaul due to storage problems,

  • Retention of original octane performance

  • Leaves no residue after combustion

  • Safe for every type of vehicle & power equipment (2 or 4 cycle)

This is an essential product for cars, boats or lawn mowers that "sit" for long periods.  It is great for holiday homes where you leave a car or boat or any other engine.

For more information on PPC’s amazing range contact either Rob Harrington-Johnson or Kalinda Ross on 1 800 643 229.

Marine Batteries - Maintenance for your Boat Batteries

Written by boatplace

 

How often do you service your boat's marine batteries?

Yes, I deliberately used the word 'service' to catch your eye. Because chances are you might check your boat's engine oil levels. You probably monitor your boat's power steering fluid levels and the gear lubricant levels. You might check the belts for tension. You might even monitor salt and corrsion build-up on parts of the engine and clean and spray with anti-corrosio paint.

But how often do you think about checking your boat's batteries. They need some attention too, but are easy to forget about. After all, it's boat engines that are the big ticket items that we worry about having to replace. But given some basic and routine maintenance, marine batteries can enjoy an extended life and you can be rewarded with lower operating costs in not having to replace them earlier than otherwise required.

Basic maintenance for a marine battery involves observation more than anything. Most of the time you should not need to do much, or anything at all. But you should make it a priority to check your boat's batteries as part of your basic maintenance routine.

The terminals on a marine battery can oxidize the same as a car's. This means you need to check the battery terminals regularly for corrosion, especially if your boat doesn't get used often. Corrosion can appear as a build-up of white powdery deposits around either or both of the battery terminals. There can also be a bit of color mixed in - a bluish-green tint. These deposits can be the result of chemical exchanges involving vapors and the battery terminal.

Directions for inspecting and cleaning you boat's marine batteries:

  1. Remove the battery box cover/s. Disconnect the battery cables from the battery terminals by loosening the nut on each cable clamp. Once they are loose, always ensure you remove the cable clamp from the negative terminal first. It’s marked with a minus (-) sign and the positive terminal has a plus (+) symbol. The cables may not lift off easily and may need to be gently wiggled free until the clamp comes off the terminal. If there is a lot of corrosion present, you may need to use of pair of locking pliers. Be careful not to short any spanner or tools you use against the nearby metal objects when they’re in contact with the marine battery.
  2. Secure the loose cables using tie and duct tape so that they cannot accidentally fall back onto the terminals.
  3. Examine the condition of the battery cables and clamps for corrosion or excess wear. Should any damage appear extensive, immediately replace the cables and clamps to avoid potential problems.
  4. Check the battery's casing for cracks and the battery terminals for signs of damage. If you find either, replace the marine battery.
  5. Mix a small quantity of baking soda with water and paste directly onto the terminal posts.
  6. Dip a toothbrush in water and use it to scrub the baking soda into the terminal posts and cable clamps. Skin and eye protection should be worn.
  7. You can also use a battery terminal cleaner brush on it. Clean the insides of the cable clamps by using a clamp cleaner or use a plain soap-free steel wool pad.
  8. Wipe the terminals, battery cover and cable clamps dry with a clean, disposable, lint-free rag.
  9. Use a product like CRC Battery Terminal Protector or Lanox. This comes in an aerosol spray pack and provides a protective film over the terminals to reduce the liklihood of corrosion build-up. Cover all exposed metal surfaces on the battery posts, battery cables, and clamps.
  10. Replace the positive clamp first and then replace the negative clamp. Tighten them securely with the spanner and replace the battery box cover.

Checking the electrolyte levels in a marine battery.

Remove the vent cap/s. The fluid levels should just cover the interior lead plates and distilled water (available at all supermarkets) should be added if fluid levels are down. You should habitually check the marine battery's electrolyte levels whenever you are checking your engine oil and lubricant levels in the boat. There is a fill well visible underneath the vent cap. Fill the well to cover the lead plates, but avoid overfilling the battery. Always use distilled water for servicing a marine battery. Ensure the vent caps is replaced and tightened after checking the fluid level. Never add acid to a marine battery.

How to repair fibreglass boats

Written by boatplace
Boat Repairs - Fibreglass Repairs for boats
Back to Boat Editorials

Boat Repairs provides information for fibreglass and timber boat repairs, restoration and modification. Service providers might include shipwrights and workshops that offer a specialized service for boat repairs.

Fibreglass Boat Repairs for all boat and marine fibreglass repairs and information.

Fibreglass repairs have long been & still are a complex & tricky job, hopefully this article will explain some of the problems you may experience.

Step 1. When grinding the f'glass back for preparation it is imperative that you remove all delaminated areas. All edges should be feathered out so no sharp edges remain. At this stage you should apply resin to the area to soak into old laminate & act as a primer. Allow to dry 1 day

Step 2. Laminating the damaged area should result in a flat finish & replicate the original surface, polyester resin is the most commonly used resin in production boats & chopped strand mat is also the norm. Allow to dry 1 day

Step 3. Sand the area & apply enough filler to bring it to just above flush. Ultimately you should not be using too much filler as this will result in cracking at a later date. Filler can be bought from f'glass suppliers or as we do, make our own. Sand the filler back with a block to attain a flat surface, even on raduis or inside rounds.

Step 4. Applying the gelcoat to the surface can be done by brush or spray application ( as we do) the trick here & probably the most difficult is getting a perfect colour match! Some f'glass suppliers will match colours at a cost!! allow to dry 1-2 days

Step 5. Finishing> This is where all the skill is involved & again using a flat block to achieve a flat surface is important. Starting with a medium grade freecut sandpaper (220 grit) & working down through the grades to 1200 - 1500 wet & dry then compounding with a power buff.You should then apply 2 coats of wax for a perfect result.

As you can see there is a lot of labour involved but there are NO shortcuts!
