Yes, the engines were running smooth before the new plugs. I checked the lower helm tachs against the timing light and they were off by 100 RPM or so. Funny thing is the flybridge tachs seem to match almost exatly. It is tough to tell a 100 rpm difference though. Without buying a floscan I am wonder...

Ok, first let me report that we had some success. 16 new sparkplugs and nothing else. Port motor ran up to 4600 RPM, starboard motor up to 4200 RPM equated 25 mph. New wires, cap and rotor this afternoon. Hopefully will get equal performance from each motor. Huge improvement already though. My mecha...

Transmission levels checked out. Motors seem perfect at idle or putting along. docks great, props bite hard and drive system reacts well. Boat is a dream in close quarters. Motors spool up instantly in neutral, 4000-5000 RPM easy and almost instantly. Never tried to max them in neutral. Motors start...

just got off the phone with my mechanic. Timing is good and advancing properly. Electronic ignition - standard mercruiser ignition. At this point I am concerned about a water logged hull. That would be a worst case scenario. Perhaps the carbs need rebuilt from sitting from the previous owner. Or a t...

dove the boat yesterday before we left the dock. Ex U.D.T. and recovery diver. One question though, there are no zinc's on the shafts. Never have since I've had the boat. I know it is a different subject, but is there a simple answer? Zinc's are on the rudders and tabs. I took notice as well of capt...

no improvement. 2600 RPM max and still only 11 - 12 mph. Exhaust smells rich, heavy gas smell, at max RPM's. Timing was just re-checked but perhaps the points are bad, gapped improperly or for some reason failing. I will check the distributers more thoroughly and may replace. Any advice is welcome. ...

come on down, I would welcome the ride along. Lunch is on me!

gps works fine, I just paid little attention to speed. Plowing for sure. Bow reacts as it should, rising and falling in relation to the the tabs.

truthfully I am not sure, I think about 10 or 11 mph. When plowing like this I move the tabs up and down and watch the bow and wait for her to pop up. I give up pretty quick and just settle in instead of continuing to waste so much fuel.
Thanks mucho on the well wishes. Will keep you posted.

I did seatrial the boat, motors ran smooth, compression checked out - would not pass 2200 rpm port motor and 2500 on the starboard. Great price - I bought the boat. Re-adjusted the throttle linkage, got the current 2600 RPM from each motor. Transmissions are 1.52:1, 16x16 props. bottom and gear is p...

timing checks out, filters new, anti-siphon may be an issue. how do I check? Engines run normally while not under load.

I have a 73 F32 with newer 350's approx 320 hours. I bought the boat recently. Previous owner said props are original. Engines check out great, compression perfect, bottom clean. Starboard motor runs clockwise, port motor opposite. Tabs functional. Can anyone tell me what the correct gear ratio tran...
