    2002 225 Optimax - Overheating at idle only

    In that case, I would say it is a stuck/bad poppet valve.

    2002 225 Optimax - Overheating at idle only

    Is this engine ran through saltwater, sand, or mud?

    115 Yamaha overheat alarm at 1,800 - 2,000 RPM's

    The idle RPM tangent got me side-tracked too haha. If your engine is used in saltwater you need to clean out all the deposits from that, kind of like you did when you took the heads off. To do this you need some Rydlyme marine and a bilge pump or livewell pump to pump the Rydlyme through your...

    High compression in 1 cylinder - 7.4 carb

    Like Scottin said, the cam is actually way different. Marine cams are built with all low end torque in mind, similar to what a truck is. A cam from NAPA would leave you with a gutless boat engine. You need a marine cam and they are more $$$. Additionally, depending on where your engine is...

    Alpha One 3.0 Starter questions

    Is post number 2 viewable to anyone else? Lots of people buy amazon starters. They buy them every year because the starter they buy off amazon quits working after a year. Smart strategy by amazon selling you a new cheaply made product every year. I don't consider a starter on an inboard "small...

    High compression in 1 cylinder - 7.4 carb

    That wouldn't cause it to tick like it is though would it? If that cylinder is not firing properly, stuff is going to build up in that cylinder wouldn't it? Check the pushrods first before pulling the heads off. Roll the engine over with the valve cover off to make sure your intake and exhaust...

    High compression in 1 cylinder - 7.4 carb

    Like others have stated, it sounds like you have a flat lobe/lifter on the camshaft. Pull the valve cover and inspect the exhaust and intake pushrods for cylinder 8 to see if there is any play in them. Is it a flat tappet cam? Flat tappet cams require oil with high zinc/ZDDP. I found that out...

    Blogs plug housing loose and turns

    You can quickly check how much of your transom is rotten like alldodge said to do very easily. Take a hammer and just start tapping around the transom from the inside of the boat and outside. Tap on the stringers too. If they are rotten, it will make a dull, soft, quieter, thud sound. Harder...

    Need help with Hull crack in Aluminum Lowe Boat

    To echo what they said and to add on, if you want to save some money, remove the bow eye for the weld shop and brush the crap out of the area that needs to be welded with a wire brush (SS wire preferred) to remove the paint and corrosion and other nasties. That will save the shop prep time which...

    Livewell Pump Noisy

    It could be normal, it could be about to die. It is impossible to tell without a video or audio recording. I say if it works, leave it in. I have a spare livewell pump always with me cause they go out all the time.

    Overheating at idle

    What is telling you that it is overheating? A gauge? An alarm? Have you confirmed the temperature with an IR thermometer?

    Yahana 200hp txrr stumbles at idle

    This. Draining the fuel in the bowls and spraying carb cleaner in them is almost useless. The carbs need full disassembly and every square inch of the inside cleaned.

    Overheat alarm at idle... I think??

    Are both your oil resevoirs filled? Are the oil float sensors floating in the oil?

    2008 90TRL need more power!

    An 18 pitch prop would be about right for your boat and engine combo. Even if it was repitched, don't they only change it by up to 2" on stainless or so? I do not think the root of the issue is a prop problem. 16 to 20 pitch will be ballpark the correct pitch. 90 PSI, if your pressure gauge is...

    1999 Yamaha 115 idle adjustment

    I just bought the 130 outboard a month or so ago. The oiling system I believe worked, but I never tried it. I deleted it because when I go fishing or hunting, I want my stuff to work. I have been told that the Yamaha outboard oiling systems are great too and that I did not need to delete it from...

    1999 Yamaha 115 idle adjustment

    On a car when an electric fuel pump goes out, you get a ride home from your nearest buddy for free. On a boat when your electric fuel pump goes out, you call 1-800-boat-tow and shell them $2k. Okay maybe exaggerating, hopefully you have a kicker, but crawling home on your kicker over a bar is no...

    Low Compression, Low $ Advice

    Thank you for all the responses y'all! Incredible help! It seems like the consensus is a full rebuild rather than honing and new rings, so I will save some $$ in the mean time. The funny thing is, I posted this thread before I took it out on the water. I bought it as a "mechanic special" and...
