    1993 Mercruiser 4.3 2bbl carb running out of power

    did you pass a fine wire thru every passage to make sure they are clear? you need to do this. let me guess, the pinesol thing was on youtube? if so, ignore it. get a container of barrymans carb cleaner (since you can no longer get the good stuff). I have also used acetone or lacquer...

    1990 Mercruiser 3.0 (Prestolite not Delco) No Spark

    do you understand points ignition? there is no power. the points only open and close the ground path to the negative side of the coil. the ignition switch provides power to the positive side of the coil thru two paths, path 1 is direct from the starter I or R terminal to provide full battery...

    Help! 1976 Mark Twain restore it or junk it?!?

    I removed the cap on one of my restorations by using the garage rafters and 5 ratchet straps. after building a cradle on the trailer, I undid the rub rail, went around with a steel putty knife and a pocket knife to separate the sealant on the rub rail seam, then slowly lifted left the cap...

    Mercruiser 470, hero to zero. Timing chain jumped?

    I would look at fuel system first. its not probable, however it is possible that the timing chain is worn enough to jump you can verify the timing chain with both engines there by simply pulling the valve covers and putting a dial indicator on the #1 rockers. using a tape measure, start at...

    Oversized Valves needed for Mercruiser 140 3.0L

    ^+1, what he said. bronze guides are extremely common repair take cylinder head to real engine building machine shop. day later, pick up cylinder head and install. however the cost of doing that is about same as getting new head which is more than buying a newer used motor

    Volvo sx drive - delayed reverse, doesn't seem fully engaged in forward

    if your shift linkage is not adjusted, you could have toasted the cone clutches if your mechanic used the wrong gear lube, you could have toasted the cone clutches you adjust the shift cable back at the drive stop using the boat until you figure it out.

    Used Maxum

    its a 21 year old boat (which means consider it a project). so condition means everything other than that, Maxum no longer exists as a brand. it was a low-level brunswick brand (bayliner/searay/maxum)

    ANOTHER WATER IN OIL QUESTION

    run your water jacket pressure test at 15 psi. should hold indefinately the water in the manifold may be a secondary issue. how did you winterize? Eastern NC got well below freezing this past winter a few days.

    Water inside boat

    first, welcome aboard second, remember, boats are designed to last about 15 years and be replaced as they start to fail a few items that can cause the water leaking as you describe: leaking rub rail that only leaks when you cut to port due to water splashing up the sides of the boat crack in...

    Wayyyy over propped???

    goes to show how much BS is on the internet. your cranking PSI is ball-park your compression ratio times 1 atmosphere. so a 9.5:1 compression ratio will be about 140 psi. it was true in 1862 and when Nicolaus Otto built the first 4-stroke in 1861, it is still true today. from the Yamaha 250...

    Cobalt 232 swim platform repair

    you made more work for yourself now that you cut the skin vs separating the skin at the seam. like AD stated, the force prior was only a few PSI over the whole surface, now its about 15 times that, concentrated over the seam you cut. you will need to bevel back the remaining skin about 3"...

    Wayyyy over propped???

    no way your compression is 200. you would need a diesel engine to have compression that high. check your gauge
