    mercruiser 4.3 overhauling

    No those are rollers. In general pretty much have seen that rollers can be reused with different cam etc. my other hobby is a 65 GTO, guys reuse roller lifters with different cams all the time, it’s seen as an advantage going with a roller , which on a pontiac V8 is pricey. Buy a good set of...

    mercruiser 4.3 overhauling

    As SD nmentioned same roller. You can use rollers on any lobe used or new. The comment in the manual is for hydraulic flat tapped cams where the lifter wears in to a specific cam lobe

    100% he will have enough slip with any of these aluminum props that if pitch is right he will get the holeshot he is looking for. my 23” spitfire AL 4 blade has almost identical wot rpm as my 21” Revolution 4 …

    yes usually as you go down in pitch diameter tends to go up. None of these aluminum props are going to have so much bite that they will not turn, worry about that when you go with the higher end SS props. check out mercs prop selector will make some general recommendations

    Prop Selection - Bayliner 175

    that is a good step wise approach. For sure a 3.0 will not be barn burner. I ran mine pretty hard for 20 years (was 5 yrs old when we got it) and it was still running great when I sold the boat. Was a great starter boat an I cut my teeth on boat maintenance on it, never broke the bank

    from the 90's no - the 3.0 is a descendant of the 153 cid /2.5 l that debuted in the 1962 chevy II (aka nova)... Before you get too worked up check you compression tester vs another gauge. the 3.0 I believe is 9.0 or 9.4:1 hence the 150 psi cranking pressure, older higher compression engines...

    Lexus Oil Leaks and Mechanic (Woes)

    Yes you absolutely never want to self diagnose the issue and ask them to do specific tasks. on Toyotas the PS pump is usually down there and hose to reservoir can be a leaker. take it down there and face to face ask them to look at it may be a issue from their work or may be a different...

    My Skag got worn down, I had a power failure

    this. it dies protect the prop but you wont notice it. In the future you can always pop the trim rams off the back of the drive and hold it up with a rope in case of failure

    I’ll play the other side of the fence… do not mean to imply that other advice given is bad, just some of my experince in a similar boat is different. Like you my last two boats are primarily used for loaded down watersports. Previous boat was a 1991 sea ray 170 3.0lx 135 hp, current boat is...

    Timing is retarded ;-)

    No I couldn't go over 5k much with the 17" could only tap it if gas tank was empty and trimmed out. Only downside to advancing the timing would be detonation potential, if you already bought the module it is a moot point

    Timing is retarded ;-)

    have you verified the tach at 5300 is accurate? I don't think the est has a rev limiter, so if you are indeed hitting 5300 watch it as that is above the safe limit for the 3.0. I had a 91 Sea Ray 170 which is a similar size boat and ran 17" and 19" props and was no where near 5300. This 3.0LX...

    Does it work with the trailer button ? If so your trim limit switch is bad

    Timing is retarded ;-)

    The ignition module is available separately. I think if you google delco est module you will find the cross over to the GM module. you are correct to do some basic items if maintenance was neglected. I would hold off on that for now… if you have the wrong prop that will make an underpowered...

    Trim troubles

    The solenoids will click. A continuos hum is the pump working. hard to tell from info given. A volt meter and wiring diagram is needed if pump not running. If pump is running have you checked fluid level and condition

    Alpha outdrive stud came off with nut. Never saw this before???

    Exactly just have to know what type is used and what heat is required to remove. Even their 660 retaining compound breaks down after a year in heat of machines

    Leak into bilge, bellows?

    Bottom line with a scope Carmera attchment etc you need to get back in there and look that’s the only thing that will show you this. lift drive full out and double check the bellows both driveshaft and shift. The driveshaft can get splits on the side where it rubs on gimbal ring. Can also pull...
