    Check valve and filter assembly

    Can someone tell me the purpose of the check valve and filter assembly on my mid 80's, Johnson 110hp outboard? It threads into the engine with about 1/4 inch diameter threads and has a very small nipple at the other end. A hose pushes onto the nipple. There is a small filter screen inside...

    Best prop?

    Greetings, recently purchased a 21ft pontoon boat with 19inch pontoons. Motor is a 80hp Yamaha, 4 stroke, carbed. Previous owner told me he put that motor on the boat and that it came off of a fishing boat. The prop is a 13x19 and needs replacing. Since the motor was on a fishing boat, I'm...

    Flush kit install

    Thanks for the info on the plastic fitting. I will definitely find a metal one. I know that I need to install the y-tee between the outdrive and the water pump but I was wondering if the larger (I believe 1 1/4 inch) hose is the correct one or is there another that I'm not seeing? The boat is...

    Flush kit install

    Looking for direction on installing a fresh water flush kit on a 2007, 24ft Rinker, deep V with a Mercruiser 350 Mag MPI. There's a larger red hose , maybe 1 1/4 inch ID, that runs along the lower starboard side of the engine. I'm guessing that it runs from the transom to the water pump? Is...

    Yamaha 80hp, 4 stroke runs rough

    Here's the history. recently bought this pontoon with a 2001 80hp, 4 stroke Yamaha. Knew it had an issue when I bought it. Previous owner brought it to a local marina and they said it needed the carbs rebuilt. After sitting at the marina for weeks without getting worked on, the owner went and...

    running rough

    Update. Let the engine run for a couple of minutes and did another compression test with the idle lever fully lifted. Compression was 190, 200,190 and 190. Will order rebuild kits for the carbs and attempt to clean them? Any pointers on that would be helpful.

    running rough

    Just purchased a pontoon boat with a 2001 80hp Yamaha 4 stroke. Motor looks very clean. Knew it had a problem when purchasing. Previous owner said boat was running fine for months then problem occurred where it wouldn't get over about 1200 rpms. They changed the fuel filter and fuel lines...

    Only runs when cranking

    Well the boat is running and after a few days of searching for the problem, I am still at a loss as to exactly what it was. The purple wire from the ignition was definitely losing power but not quite sure where. As I mentioned, the boat was trailered through a terrible rainstorm without the...

    Only runs when cranking

    Here s where I'm at. The ignition switch seems to be ok. It's a three prong switch. I have constant power to the red terminal on the back of the switch, power to the purple wire when the switch is in the on position and power to the yellow wire when in the crank position. All gauges work...

    Only runs when cranking

    Have a Mercruiser 4.3 ltr, 1995. Recently purchased, clean boat. Carbureted, electronic ignition. Had it on the lake and was running great. Trailered it home during a severe rainstorm and got lots of rain and moisture in the engine compartment. Went to the launch a few days later and it'll...

    What is inside the toon?

    I had a similar issue with my pontoon. Took on water from on the top of the pontoon where the toon is welded to a support bracket (small crack in the weld). Put a small tube into the access hole which is designed for this purpose. The tube only went in an inch or so. Needed a smaller tube...

    65hp evinrude no power

    I'm going to see if I can switch out the bottom carb with the top or middle carb and see if the problem stays the same or moves to the cylinder that gets the bottom carb. That should tell me if the problem is in the carb or within the motor itself.

    65hp evinrude no power

    How can the pistons be seized yet running fairly well on 2 cylinders and have 140 compression on the 3rd? The paint was not scorched on the head but it did get hot enough to melt the poppett valves. Once it overheated to the point it stalled, I never attempted to start it again until I...
