    Air don't freeze... RV antifreeze DOES!

    For sink traps we always used kerosene. That never freezes. I used automotive antifreeze in my I/O. I would use it straight out of the bottle, and recover it for reuse in the spring. It also gave rust protection to the cast iron block.

    99 Johnson 150

    That looks to be the 60* V6 motor. A very good motor, with a proven design and proven ign, gearcase and fuel systems. I have the 1998 version and it runs very well. The only weak point is that the plastic carb bowls can warp. They must be replaced at that time, which is a drag.

    Permatex Aviation Gasket Former.-

    I doubt the Permatex caused the thread strippage. It did cause the rest of the mess, however.

    Oily exhaust water

    Also, check the fuel; pump. If the diaphragm develops a hole, raw fuel is allowed into the crankcase, and can cause the symptoms you see.

    When was the last time the carbs were overhauled? Maybe the carb is flooding?

    Maintenance manual needed

    Motor wiring diagrams are usually motor and outdrive specific. Boat wiring diagrams are boat specific, but not complicated. FourWinns were V-P at one time. What do you have?

    trailer dolly?

    People use garden tractors to move boats. BTW - A 20' trailer will not fit completely in most std garages., due to its tongue length.

    mercruiser I/O trim sensor

    So, if you had them apart, use a test light or ohmmeter to trace the wire from the inside of the boat to the trim sensor. BTW - those trim gauges when new are not real accurate. The best you they do is tell you when your outdrive is all the way down or all the way up. Both of those you can...

    mercruiser I/O trim sensor

    Alpha one drives have the trim limit switch on one of the outdrives pivot, and the trim sender on the other outdrive pivot. Pull off the plastic covers over them and you should see what kind of condition they are in, and which is which. Since they are exposed to the water, they can degrade...

    Boat Wiring Help

    First, I would not think you will want the trolling motor and OB on the same battery. They should use different kinds of batteries. Also, the trolling motor uses the most power of anything you have and will run the OB starting battery down. Second, that three switch setup will get you what...

    Motor opinion

    Compression gauges need to be accurate and reliable. Most (due to their cheap construction), are reliable, but not accurate. That is that they show the same compression number, for the same compression pressure. So, most often, if a motor's cylinders are within 10-15% in compression...

    Update on my electric fuel pump installation.

    Most OB water pressure gauges are mechanical, at least those I have seen. They cannot power anything.

    Update on my electric fuel pump installation.

    So you need to remember to turn it off, if the fuel line leaks and the engine stalls? If so, that is a safety issue. Consider that you if hit something, the fuel line breaks and you are too dazed to turn off the fuel pump at the switch. Not unlikely in a collision scenario. if you have a 4...

    Update on my electric fuel pump installation.

    OK, electric fuel pumps work well. How did you wire it in safely? If the fuel line breaks and the engine stalls, does it continue to pump and fill your bilge with gasoline?

    Nitro boats use balsa wood?

    Gee, I hope not. Every boat I had which used balsa had lots of rot in it. Luckily it was just hatch cover guts. If your transom is balsa, and it got wet, it will be mush.

    Inboard Engine Cover is Really Heavy

    Likely not 1/4 plywood, as it is not strong enough. On a cover that size, even 1/2 plywood would need reinforcement, across the short side. Best to pull the vinyl off and see what you have. 1/2 plywood is easily replaced, and can be made as well as the original.

    Early 80’s merc 2.0 150 V6 brown band clamshell black max ratio

    QBhoy Clamshell cowling found on 80's Merc 150s swing open from the front. The style solid cowling in your picture looks like my '93 Merc V6. The decals also look like the early 90's motors. My motor has a 2::1 gear ratio, but the gearcase is from an '88 Merc 150V6. A silver disc on top of...
