    Mercruiser 3.0 140 Timing Confusion

    Yeah or if there is a limit inside that is broken. Usually there is some physical stop for the weights. If you find an old school hot rod shop with a distributor machine they can probably reset the curve for you

    Mercruiser 3.0 140 Timing Confusion

    Seems like 28 advance is way too much. On some 3.0s that blew head gaskets due to detonation they had mechanics reduce te intial advacne to 1 ATDC so if you really are getting 28 mechanical advance you can reduce your intial to keep total under 30. Maybe someone put lighter springs in it to get...

    3.0 running hot 200F

    no its not ok- should be running around 175 at most. Do you know if your gauge is accuurate ? Was the impeller you removed intact or missing pieces. I assume you got hte water tube in the drive back in correctly, may have some pieces of the old impeller in the powers teering cooler or in the...

    Starting a long sitting, 2003 Mercruiser 3.0 alpha one, with a gen 2 sterndrive.

    Agreed just change it and go. I've had engines sit for that long and run just fine. I usually take the plugs out and run it on the started until I see oil on the rocker arms

    Going electric vs marinas

    My dads tesla take 70 amps for the fast charger. When they visit it is an overnight charge from my 20 A 220v compressor outlet. So they defintiely would have to upgrade service and distribution. Just like with cars as they become more prevalent the charging services will follow.

    Repowering 97 crownline. Best options?

    One thing I wish I had done when I did mine is put a remote oil filter on it. I think its like $200 to mount it up on the manifold vs under the engine.

    2009 regal 2000 rx 220 hp mpi

    I would drop down to a 17 or 18 if going from 3 to 4 blades assuming your tach is accurate (might be worth a sanity check with a shop tach). For watersports I had good luck with michigan votex 4 blades and its a cheap whay to cut your teeth on prop swapping . What SS 3 blade is the loaner...

    Repowering 97 crownline. Best options?

    Maybe the oil was never changed by previous owner . Simplest way is to order a long block either new or reman from a place like michigan motorz and have your mechanic swap all the externals Over.

    Fuel burn with 5.7 LX mercruiser, 24' Boat

    4600 is ok but you dont want to go lower in RPM. If you are hitting 4800-4900 this is perfect. Actually you are better being slightly underproped than over propped. While yes you have to watch the WOT rpm when lightly loaded, you wont risk lugging the engine, and general performance will be...

    Fuel burn with 5.7 LX mercruiser, 24' Boat

    bellow trimming wont make much of a difference in that combo. The rpm difference could be more related tot he blade design specifically how much cup it has. you may have had less slip with the old one vs the new one.

    looking for new prop

    it is a starting point for next prop selection. Your tach is off as an rev limiter will kick in at 5200 or so. What your current prop pitch is and your current wot rpm will determine what you do for the next prop. for example if yiu are running a basic three blade like a blackmax - say 19”...

    Is it worth it to replace the voltage regulator?

    Its not that hard to do im sure you can find some you tube videos . if i had a spare one id swap it on Vs reworking. If you do tear into it id recommend replacing all wear items in there vs just replacing the one component
