Hey guys,
New here. Appreciate the help..
Picked up a 1986 Bayliner Trophy cuddy with an inboard Volvo Penta AQ125 (I believe).
Everything works perfect up until I try to go over 2000 rpm. Then the RPM gauge goes bonkers.
I went through all the effort of trying to locate a bad connection etc... Ended up running a new signal wire to the ignition coil and direct connections to the battery.
No difference.
Installed a new tachometer, no difference.
Replaced the ignition coil, no difference.
So due to not being sure where my rpms were, I didn't really push the boat beyond the wacky zone. I've taken it out multiple times just slowly (about 7mph) with zero issue.
I'm now at the point I want to take it out to the islands and need to make sure this is resolved and I can also push the engine.
When I tested it, I would push the boat further into the zone where gauge goes bonkers without feeling any difference in the engine.
Wasn't until today that I replaced ignition coil that I feel like I can feel the engine running differently when over 2000ish.
Any suggestions as to what to look for?
From. What I know, previous owner replaced the alternator and spark plugs shortly before I bought it from him.
