    4.3L mercruiser with points. Timing question.

    rear main seal. I believe Scott Danforth was mentioning the fact that the first year for the 4.3 in 1985 is the only year that used a traditional 2 piece rear seal vs the more modern single rear main seal. If you have been running that much timing for 5-6 years and were detonating I think you...

    4.3L mercruiser with points. Timing question.

    Was wondering if you are running overly rich and this need more timing. Would at least watch the plugs for signs of detonation if you are bringing in more total timing than stock. Would keep an eye on this as you work through things I know when I bought my new base engine warranty stipulated...

    Have you verified the Val vet has not slipped and tdc on balancer is actually tdc ? What do the spark plugs look like ?

    Spare battery

    Agreed would not route them where they can be under water if boat fills up.

    I got got on a new purchase

    You could do that but only makes sense if the stringers and transom are good. Likely will need new engine stringers for the side mount on the 4.3 vs the front mount on the straight six. personally I think you would be better off finding a more recent boat with a cracked block or dead engine to...

    Did you check to see if the engine was hydro locked? Take plugs out and look for water in cylinders

    Carb issue.

    Obvious float needle seat issue. Hard to say what is wrong with out pics. I might be worth sending back to shop if you can’t get it. But it sound like you need to empty and clean fuel tank and system.

    Hard plane after switch from points ignition

    Generally Sierra is considered better than other aftermarket items but even oem can deliver a bad part None of it explains why the timing is retarding

    Marine Tex on Alodine?

    No you rinse with water in between any residual water is no different than the water you are diluting the Alodine with. Prob biggest key if spraying is to keep it wet for process time. Then don’t let it dry before rinsing

    Merc 4.3 TKS dying at idle

    Try adjusting it before tearing it apart but rebuild is likely . you dont need the manual to do a tune up. Tune mix screw out half a turn see what it does. If you keep track of changes you make you can always set it back to where u started …

    Hard plane after switch from points ignition

    Is this a true Delco eat or one of the aftermarket knock offs? If u paid with a card dispute the charge they should understand that something is wrong timing wise

    Battery powered pressure washer

    unless it works better than the royobi one i got a few years back keep going to the car wash. I was pretty disappointed. It is more of a wetting machine than a pressure cleaner. cant see it doing you any good, although boat would go faster due to wallet being lighter

    Mercruiser 3.0 diagnosis / serial number decode

    Better yet use the OEM bellows. I changed mine last year- 18 years old the drive shaft bellows was just starting to look chaffed on edges of ribs, exhaust had already given up the ghost. I figure while they are pricey I will not own the boat next time they need done...

    the seal in the upper that seals the vertical driveshaft in the bottom of the upper unit. Common for that seal to go and leak gear oil down the shaft.

    Alpha One Clicking in Forward, Stalls in Reverse

    I'm not sure. Elsewhere in the manual is a procedure to measure the angle it takes to shift the drive. I think this is used to check for wear to shift components inside the drive. Might be worth looking at but would try moving it on the slot to see if you can get it to work. You said this is...
