    My block is drained, right?

    Crap, dump some full-strength antifreeze into the block and manifold hoses and watch for it to emerge from the drains. It will push out any residual water.

    cold weather break in

    When I had my MerCruiser, I wired a 40W heating pan under the oil pan. When temps were cold, I would plug the heating pad in several hours before use, to warm the oil. 40W was not enough to do anything but warm up the oil and help keep the manifolds from freezing.

    Fuel starvation conundrum

    Lou, You might remove the antisiphon valve and replace it with a straight pipe for a test. Sometimes that can cause just a bit too much restriction. I cannot run an A-S valve on my 150HP Johnny OB. At high RPM she starves of fuel. I tried replacing it, but no dice.

    Fuel starvation conundrum

    OK, another SWAG. My '88 SeaRay had a filter in the fuel pickup tube. You needed to unscrew a plain tube of aluminum to get to it. When it partially clogged, the motor only got enough fuel for low to medium speed.

    Both Ethylene Glycol and Propylene Glycol are alcohols, as are all glycols.

    Fuel starvation conundrum

    Did you hook up the remote tank to the water separator? The water separator is clean and sans water? Does the fuel pump have one of those porous stones on it? Does the carb also have a paper filter on the fuel inlet? My '88 MerCruiser 4.3LX did. They last a long time, but not forever.

    Parts Diagrams for Four Winns

    Is your steering hydraulic or mechanical? If mechanical, is it rack and pinon or rotary? If steering is hydraulic, can you bleed it?

    Bad Gas

    You can usually pour off the water and use the gasoline. Put a bit of 2 cycle oil in the mix to color the gasoline and ethyl alcohol, as the water will not change color. In a 5 gallon Jerry can, you could dose it with an oz or 2 of the 2 cycle oil, stir a bit and wait for it to settle, and...

    Power trim for Mercury 200 1983

    As far as I remember Mercury OB's used those two hose, pump-in-boat style for just a few years. The earlier PTT pumps were 4 hoses (out of the control valve) to the PTT cylinders, and the later (and current) PTT units were mounted between the transom clamps. I do not know if the MerCruiser PTT...

    What kind of oil should I use

    If your oil specification is FC-W, like a lot of 4 cycle OBs, that is what you should use in the specified grade. Automotive multi-grade oil is not usually recommended.

    Trim gauge not working

    You might like to check the ohm range of the sender on the motor. That range seems too limited. Some of the Mercs did not have factory senders, so you might have a look at it.

    Have a live mouse inside a interior wall. No insulation.

    Gee, when I tore out the paneling in a house I just bought, I found about 6 dried mice bodies, suitable for Egyptian tombs. I was happy to get them out.

    Trim gauge not working

    Gee, you might tell us the make of the motor. Trim senders are usually a variable resistor. As the motor trims, the resistance to ground changes. The trim gauge has basically the same movement as a fuel gauge. Trim gauges need power, ground and the sender wire. Tan is usually a warning...

    Evinrude or Suzuki

    You did change the oil filter, when you changed the engine oil, right? Pump grease into the grease fittings and clean and grease the steering rod, if you have one. You rinsed the powerhead, right? Spray it with corrosion guard stuff.

    Gas Pressure washer "turn off" instructions incorrect??

    Gee, I do not use small engines very often or for long times. The only ones I have are 2 chainsaws and a pressure washer. Anyway, the chainsaws get whatever fuel I have laying around from the last use. The fuel is sealed in soda bottles for years, so it has to be good, right? I did clean...

    Gas Pressure washer "turn off" instructions incorrect??

    Gee, I put a short garden hose (washing machine hose) on the pump, stick a funnel into the upper end and dump in some windshield washer fluid. After it stops draining, I blow some compressed air into the hose, blowing out any water and fluid. I cover and store it outside.

    Transom bolt pattern for older (1983) 50HP 4 cyl Mercury with power tilt and trim

    Gee, how about some 1 or 1.5 inch lumber spacers to allow clearance for the cylinders. S/b under $10 I would think.

    96 Mariner Magnum 3, 150hp: Quick Help

    Sorry, I do know understand your last post. As far as I know you, and a guess at your question, you need the flusher device to flush the motor. The cap on the engine oil reservoir is to refill it, if it is low. Not all motors had the in-boat reservoir, and sometimes the reservoir refill...
