    Winterization Question

    If you intend to use a bucket of antifreeze with a hose to winterize an engine with the raw water pump mounted on the engine then Camco sells an adapter so you can attach the hose from the bucket to the input on the raw water pump.

    Oil level too high?

    This was a general statement for pumping oil from boat engines. In my old Mercruiser 5.7L I pumped the oil via dipstick then put aluminum pan under the drain plug and removed the drain plug to drain the rest and install a Jabsco drain hose for future oil drains. It looked like I got about 1/2...

    Overheating at 30mph

    I am read some people have by mistake reversed the raw water hoses and that causes issues. My two hoses are slightly different diameter so they cannot be reversed. Pull thermostat and double check in pan of hot water. Hang by a string. IR thermometer will be very beneficial for diagnosis...

    Oil level too high?

    No matter how you pump the oil out you will end up with a 1/2 QT of oil remaining. For my old boat I got a Jabsco oil drain hose that replaced the drain plug and there was a cap on the end of the drain hose. So you pull the drain hose up a bit on the side of the engine unscrew the cap and...

    Winterization Question

    If you have a engine driven raw water pump you should only use the muffs with a pressurized water source like a garden hose. Not a bucket on the swim platform.

    Exhaust elbow for Volvo Penta engine with catalytic converter

    How will it do with salt water running through it? Same issues as cast iron? Still have to replace every few years in salt water. Each exhaust elbow is $1250.

    Exhaust elbow for Volvo Penta engine with catalytic converter

    The whole exhaust is cast aluminum. Looks like cast iron but is cast aluminum as proved by a magnet. Would they last longer than cast iron? How about in salt water? Why go to aluminum?

    VP 5.7 Gi-J three or 4 sparks only

    I agree. The one that did not work properly was probably aftermarket.

    Volvo Penta 3.0GL Warning Alarm

    When you say not allowing the engine to start or run what do you mean? The alarm sounds for issues that happen when the engine is running. Clearly sensors can go bad. So can relays.

    SX-M 1.97 upper lower outer drive fit 1.79?

    Talk to the people at All American Drivers in IL or Michigan. Around there. They can rebuild what you have. You will like a like new drive with a 2 year warranty. I had mine put on a pallet, sent to them, they rebuilt it and returned it on a pallet.

    Corrosion on drive

    Did VP identify the root cause? Bad paint job? Incorrect bonding? Fresh or salt water? VP sells an OXI versions of most models for salt water.

    Corrosion on drive

    I would still go through the bonding in the boat with a fine tooth comb. I have a block in the back of the engine bay where everything comes together. OP - is your boat on a trailer, rack, slip?

    Draining the engine

    If you think about it the drain plugs for any engine will be just above the oil pan. Basically they have to be there. For manifolds sometimes pulling a bottom hose is easier than undoing a drain plug if it's corroded.

    Most boat engines die of water ingestion.
