    Odd 4.3 overheating

    I suspect there is something wrong with check balls . Thinking they are allowing too much water to go directly to elbows and overboard. This starves the block of incoming raw water Coming up from the drive. Suspect removing thermostat reduced restriction feeding water into block circ pump...

    Tahoe boat

    Tahoe is an entry level boat. They have the same mercruiser engine drive etc as other makes that are higher end. Fit and finish level are lower. Good friends of ours have one been fine for them and held up well. would definitely sea trial it, but for a first boat at a value price probably not a...

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    This is a K kit for BBC but you get the idea has springs retainers etc that should work together. Should eliminate any mismatch issues like wrong springs etc. Make sure the machinist checks the valve spring, retainer, seal clearance installed height etc. You never know what was done to the...

    Alpha 1 Gen 2 lower end oil

    I wonder if the small quad ring that seals the 1/4” oil passage between the two halves if the drive got dislodged and may be blocking the passage? Would think it would leak if that is the case. Other thought is how cold is it. if the lube was stored in a cold garage 90 W doesn’t flow very well.

    Want to verify that I have the right prop (Mercruiser MC-1)

    Q has you steered straight try the 21 it should deliver about 400 less rpm than the 17 You can peruse mercurys prop calculator but you really need current wot speed and rpm for it to be accurate. But they don’t replace real world trials on the water. Best bet is if u can find a prop shop to...

    Seadoo GTX 4 tec

    From OP - Yea that's what I'm thinking. Any way to separate? To OP - see step 5 in what AD posted. On my older sea doo the pump and impeller come out together assume it is the same? This guy has rigged up some type of puller to pull pump with impeller out of the hull. The impeller is either...

    Removing very, very, very stuck propeller (Mercruiser MC-1)

    Yes once nut is off it should slide off. They make pullers for this but are probably more expensive than the prop you are trying to save…

    Quicksilver Powershift 2

    As mentioned Enertia, or try a 4 blade. I have had very good luck with a Revolution 4 and Vensura Props. Tried a high 5 was disappointed with it same results as you. For sure you will not keep the same top end and have good holeshot with out repowering with a bigger engine… props are trade offs...

    Seadoo GTX 4 tec

    Don’t know that model exactly but Sounds like the impeller is stuck on the driveshaft. Its just pulling against the Coupler between engine and drive shaft and or the seal where it goes through the hull. driveshaft is splined into impeller, if it hasn’t been off ever may be the issue

    Mercruiser 3.0 carb issues

    Clicking seems like accelerator pump arm inside float bowl is rubbing. Take bowl top off i think you will see the arm that attaches to the accelerator pump pivot shaft is installed incorrectly. I think if it get flipped around during a rebuild it rubs the linkages seem ok, except accelerator...

    Seadoo GTX 4 tec

    Yes was also thinking pump itself could be siezed if it sat with water inside for years. Might be easier to remove pump and see if you can turn driveshaft
