    Say it ain’t the transom!

    As for the status of the transom, I can’t say; but I did find the source of my “water”. Turns out one of my trim lines running back under the gimbal had a pin hole and was pushing out foamy W30. The bilge has oil all over it. So now I’m on the hunt for replacement lines.

    Say it ain’t the transom!

    Thank you all. Good thoughts. Bondo, yes, there is a bolt missing at the flywheel cover. It went missing years ago and I just never put it back. The boat is an ‘81 sea sprite. I check the hull every year for damage, though she lives in dry storage so rot would seem odd at this point. No flexing...

    Say it ain’t the transom!

    I’m really not sure what to make of this. Running on the muffs in the driveway I have what appears to be water dripping down the transom. I checked around hoses and the exhaust and didn’t see any signs of water. In theory that should be the only place water could be coming from unless there’s...

    Tachometer bouncing

    Update and finale’ here! Found the heated air choke hose to be broken. Carb was sucking in extra air for who knows how long. Took care of that and the tach issue vanished. Still need to make some minor adjustments to the carb but all issues are now resolved. Thanks everyone for the help

    Tachometer bouncing

    I’ve got a tach feature on my digital voltmeter. I’ll hook it up and see what happens

    Tachometer bouncing

    Head bolt repair taken care of. Tach is still bouncing over 1800 RPM. I can turn the needles on the carb all the way down and she stays running! My guess is carb rebuild may be needed. Looking down the throat it’s wet at the top of the venturies. I don’t recall if this is normal or not

    Tachometer bouncing

    Guess I should have paid more attention to the Seloc manual 🤦🏻‍♂️

    Tachometer bouncing

    This head only has about 10-15 hrs on it since it came out of the shop a couple years ago. -In theory should still be good. The bolts came out fully in tact, just took the threads from the block with them. I’ll mic and check the block while it’s off but helicoiling should fixt me up. I am going...

    Tachometer bouncing

    Figured as much. Guess I know what I’m doing this weekend

    Tachometer bouncing

    Tried some higher octane fuel as it seems to have what sounds like pre-detonation. Also some possible air leaks around the intake. I’ll have to get a gasket for that. Biggest issue is I noticed bubbling around the center head bolt . -tried to make sure it was torqued to spec and when I put the...

    Tachometer bouncing

    A video tells the story. The needle jumps all over at RPMs over 1800, but it pulses even at idle with a noticeable “miss” you can hear.

    Tachometer bouncing

    Because it’s only happening as RPMs increase I wondered about some kind of electric interference. -this setup worked fine last year I’m just not sure what changed.

    Tachometer bouncing

    1981 SeaSprite Mercruiser 140 with Alpha drive, converted from points to EST two years ago. Recently when I get RPMs over 1800 the tach will begin bouncing as it works its way up to 4K. Simultaneously there is a rattling noise almost like valve train heard from the engine. (Possibly unrelated?)...

    Chattering in out drive

    Thanks I’m suspicious of the cap/rotor. Tach is bouncing all over the place as i throttle up

    Chattering in out drive

    The water tube was the issue. She’s working now. New order of business is poor performance over 2k RPM but I’ll start a new thread for that.

    Do you happen to have a link to the you tube video you’ve seen this on?

    Chattering in out drive

    I don’t have a thermostat installed on the engine, never have; it’s not right, but it’s never been an issue. I bring up the water tube because it’s happened before. When installing, the copper tube ends up being pushed too far up into the upper and doesn’t seat properly in the impeller housing...

    Chattering in out drive

    Well the good news today is that system pressure tested well, went back together; the engine started and she purred like a clatter-free kitten. The bad news is that my water impeller is not impelling. Gauge ran up to 180 and I shut her down. Maybe the water tube didn’t Seat properly when I put...
