I'll motor out to the lake side of Cedar Point Amusement Park, anchor along with hundreds of other boats, & watch their fireworks from the water. Having engine troubles last year, just watched them from farther away at our marina last 4th. Hope my starboard engine holds to see us there and back ...

Our company (mother-in-law, sister-in-law, niece) went home, so yesterday evening, with some dread, I did a compression check. Yup, the compressions are still low; in fact 5+ lbs lower than before. So, the Marvel Mystery Oil/Sea Foam route ruled out sticking rings. Will now move on to a leak down te...

Rechecked order when I did compression check. Made up tags with cyl # marked on both ends of spark plug wires when I rebuilt last year. Even have the plastic seperators so they don't get all turned around on each other. All OK.

Thanks for the reply Dan. Will look at the springs/lifters if I can't attribute the problem to ignition. They're defining western Lake Erie as that portion of the lake west of a north-south line from the Huron River.

My hull # on my '75 tri-canbin is just where Old Flame says it is, starboard side of transom, just below rub rail line.

106 was a typo. Should be 160. Brand new (not rebuilt), heads, springs, lifters last summer. If it is a broken spring, wouldn't it show up at all RPM's? Dan; I know I don't have a gasket seal for the distributor cap. Will check on that when I contact the merc dealer here. When you say ...seal the di...

What a great way to thank a vet for the sacrifice he has made!

Would that same procedure work on tri-cabin salon windows?

Didn't get to put the Marvel Mystery Oil into the crankcase until Sunday. On Saturday wined & dined my wife's cousin who came up. When I went to pour the oil in the crankcase Friday night, I saw oil/water glop on my fill caps. The water temp. gage on the satarboard engine has been reading low-ar...

Suprisingly enough, there were no noticable ridges last year on any engine cylinders, indicating virtually no appreciable wear. Cylinder walls looked in real good shape, but we didn't mic them. Not bad for 33 yr. old engines! Maybe I'll get lucky & the mysytery oil will free up what turns out to...

I put a fresh set of spark plugs in & got the timing & dwell set. Only around a 25 RPM swing on the tach needle; much better than the 200 or so swing I was seeing. I figure it was due to fouled plugs missing. Took the boat out for a test ride. Could only get the starboard engine to hold stea...

I've already gapped the points to .017. Did that Sunday. When my mechanic tuned up the engine after we rebuilt it, he found it liked the high side of the range best. Auto Zone gave me a free replacement of the AC R45TS spark plug that the post snapped off (#3 cyl). I'll put the spark plugs back in. ...

Thanks, guys, for all your input! OK - will check timing 1st, then dwell. Spark plugs out right now, will put in a fresh set. Once timing & dwell are OK, or ruled out, will address idle speed. If I'm still wavering on tachometer, will do leak down test. Oil in this engine is a little dirtier tha...

So, if it's not an exhaust manifold problem, then would bad rings be a likely cuprit? There was a lot of soot on the inside of my flame arrester. That may be from burned oil due to bad rings. If that's true, then am I looking at having to pull my block? Yuk!!!

I bought brand new (not used) heads assemblies, complete with new valves & guides.

When I rebuilt the engine, I did not see any sign of water in the cylinders proper-only rust at the bottom of #7 cyl exhaust port. If I have a crack in the water jacket, I'm wondering if that's where it is.
