    Ford block id

    Cant tell you the casting number meaning but long block or short block means is it with heads or with out. if you get a new long block that means engine block with rotating assembly and cylinder heads installed. short block is just the block with installed rotating assembly. both these terms...

    Mercruiser 3.7 (470) wont turn all the way

    I would think that means the lifter for that valve may have been stuck in the bore. Not sure if it it is an interference engine or not

    Mercruiser 3.7 (470) wont turn all the way

    I would start it up and see 90 is normally a dead cylinder, and the 115 is pretty low too... Hard to say if rings will get freed up or if there is corrosion of valve faces or seats that prevent a proper seal. Bottom line as long as it turns freely start it up and see.

    Propeller assistance

    I would consider a four blade. Like you i used to run a 17” three blade black max prop for skiing. Swapped in a 4 blade 16” michigan vortex ade a big difference in hole shot and pulling up slalom skiers with an under powered 3.0/135 hp/18 ft boat. Ultimately is it as good as a bigger engine...

    2001 Mariah Diablo 180 ?

    Looks fairly well cared for and price seems reasonable, actually cheap if you believe NADA. Issues I would be concerned with is transom and stringer rot, condition of bellows, impeller, and fuel system. I'm assuming someone redid the upholstery or it sat under cover unused. Mechanically would...

    Right side idle relief water outlet port blocked

    If it is running at ok temp and that side doesn't get overly hot ye I think you are ok. Normally you don see even flow out of both idle relief ports anyways. You may be able to see in side if you pull the drive and exhaust bellows. Biggest concern I would have is if you get a shutter logged...

    454 Lifter Adjustment

    Yes a lot of V8's like this had non adjustable valvetrain. It generally works fine as long as you don't change deck height or mil heads significantly , of the valves stem and spring is at the factory installed height; otherwise you have to change to adjustable valvetrain or use a non stock...

    5.7 ltr whining / Humming noise

    Check gimbal bearing And u joints . While doing that run it with drive off , my guess would be gimbal bearing or upper drive gear or bearing noise.

    1995 OMC 5.0L motor oil question

    True , most of the fresh water lake boats ive been around for last 40 years run fine but floors, stringers, transom, and interior fabric get roached and people move on, but engine and drive still have many hours of life left. the guy i sold my 1991 Sea Ray 170 to ( in 2016 still very nice...

    Marine oil VS Standard Synthetics

    Agree don‘t over think it. i dont think in that application (stock 4.3) you really take advantage of synthetics. Any of the mercury 25-50 or 25-50 marine oils are fine, 15-40 rotella works great. Also have used mobil one 15-40 and 15-50. you’re only putting what 75 hrs a year on it ? any decent...

    Alpha One Gen Two outdrive vibration

    roughness or binding. Kind of tough to explain something you need to get a feel for. I would also look for marks where the u-joints gimbal etc may have been rubbing on driveshaft/yokes - which is likely the knocking you hear. Also look for water intrusion in driveshaft bellows.

    Does mercruisier 2.5 have the function of overheat alarm?

    My 1990 vintage 3.0LX/Gen one had one. Never over heated but the switch failed and I had to snip the alarm buzzer wire when I was out on the water one day...

    Alpha One Gen Two outdrive vibration

    Would pull the drive inspect gimbal bearing and u joints, issue there is most likely. I assume new Drive shaft and u joints came with upper drive, but id there was water intrusion could be an issue.look at gear lube for metal pieces, shavings are normal, but chunks not so. If those are ok might...
