    Old manifold question

    I think the earlier 150 hp/230 cid version of the straight six was offered with that or a 2 bbl rochester. May have been like '65 or '66 years

    Which gasket is better for impeller install, metal or fiber?

    Good to replace the thermostat and zero the milage one wear items if you just bought it and dont have a history on it. By the dash guage my similar boat - 5.0/Alpha gen two runs about 165-170 with a 160 degree thermostat. so Id say you are fine. FWIW stick with OEM impellers, I just changed...

    Antifreeze circulation through engine

    Your plugs may be different if its older. Older ones used hex pipe plugs- there will be one on each side halfway down the block just above the oil pan rail. Not all exhaust manifold cooling fittings have plugs, you just remove the hoses to drain. The big U hose at the front of the block now has...

    MerCruiser 8.2 big block 2014 — shuts off after 5-7 min of running

    I would agree with AD you are loosing the 12 v run power intremittently, the only thing getting hit may be the breaker as mentioned. Do yoiu have power at the helm when this happens? You will need to trace this out to and from the key with a voltmeter

    Piston Damage?

    I would second this , run it. All you have to loose is the labor for cylinder head install. I had a spark plug center electrode drop out on a toytota 3.3 V6. Wife said the engine is making noise. Rattling tapping etc from top end , nothing wrong with valves, first plug I pull was missing the...

    Merc prop on VP with Hub Kit?

    yes if it has a replaceable hub you need a Michigan XHS 205 kit or Merc equivalent. these are interchangable with merc Flo Torq hubs. Unfortunatley VP and Merc take different hubs.... Heres two examples

    2002 Yamaha XLT 1200 winterization

    Thanks for the info. I'll pass that on. Its not my wave runner, I suspect my friend paid little enough to just enjoy it as is.. the PO already replaced the engine so I hope some of these things have been done already..

    2002 Yamaha XLT 1200 winterization

    Ok I was leary of just blowing the water out but that confirms it. This is in a very cold area so I think worth the $20 of AF... Is there jet pump lube to change like on my Seadoo? And if so is it obvious wher the drain/fill ports are? I havent found any youtubes on this so Im asusming it is...

    2002 Yamaha XLT 1200 winterization

    A good friend just picked this ski up earlier in the summer. He asked if I could help him winterize it this weekend. Any one know what is required? I've seen a lot of videos saying Yammies are slef draining just rev it up, which I find hard to belive. I have done my mercruiser powered boats...

    Quadra Jet: cross threaded fuel intake fitting

    depending on how bad your existing threads are the dorman piece may work better than a helicoil for you. The dorman piece should cut new threads farther in the casting, so if they arent too messed up this may be a better way to go

    97 Bayliner 1950 Capri

    A 21" in a 19 ft boat would be slow out of the hole for sure. The 19" should put you in the right direction unless it has a ton of cup (lowers slip and thus wot rpm). I would think you would gain 300 -400 rpm at WOT.

    Where do you like to prop your boat?

    Really depends on how you use your boat I’m assuming the performance currently is reasonably satisfactory? If like me you prefer more hole shot for water sports etc. It may be worth trying a set of 25s. I think some folks on here with bravo threes have had luck with the hill marine 4 x 4 set up...

    97 Bayliner 1950 Capri

    Wouldn’t assume anything, surprised a dealer would install a new engine and leave it only making 4 k rpm at wot. If you’re confident in the engine try to find prop markings or see if you can test your friends 19” prop.

    97 Bayliner 1950 Capri

    Would think it would a 19” somewhere on it there will be some markings you may have to remove the prop and splined washer to see it down in the hub on top of it first you want to verify the tach is accurate if it is truly only getting 4000 rpm then you are down on power or really over pitched...

    Mercarb idle speed screw and adjustment

    I also get the same with my Edlebrock 1409. Probably not the answer you want to hear but I suspect the passages in the accelrator pump circut or venturis dry out and have no gas until you accelerate and run some through. If it works really well in all other phases I would leave it allone or...
