All,
Just bought a 1999 bayliner capri 1850ls with the MCM 4.3L Gen+ 2BBL Alpha one gen II outdrive...
I have a few problems that I'll list here and hopefully get some input on.
So, 3 problems in order of importance:
1) When shifting into reverse if I give it any gas immediately after shifting, the engine stumbles for a few seconds then stalls. If I shift it in reverse, and wait a few seconds, then give it gas, it seems to be alright. No issues in forward gear... So I've done some reading that there are sometimes issues with the shift interrupter... but my question is - wouldn't the problem rear it's head in both forward and reverse gear? And further to the point, if it wasn't correctly adjusted, wouldn't I be in a situation where immediate throttle or not, it would stall in reverse?
2) My tach wasn't working at all. Previous owner said that it worked fine last year (but maybe didn't register so well at idle). Now after some fumbling around with the connections on the gauge cluster, it seems that upon starting the engine, it immediately goes to 2k (whereas it did nothing before), and slowly reduces to zero as throttle is applied. Previous owner said he had removed the gauge cluster to clean in behind, and might have messed something up, but I've checked wiring diagrams as per service manual and found nothing wrong... Could he have accidentally changed the pole selection dial on the back?? Would that cause these kinds of problems? Any other ideas?
3) Trim Gauge... again previous owner said it worked fine last year. Now it seems like it's pegged at something close to the 11:30 position (not quite straight up, just slightly counter-clockwise of 12). This one doesn't flick/move at all with ignition... I've read that when the trim gauge is pegged "up" that it's more than likely the trim sending switch... However... what exactly is the definition of "pegged"? Is it pegged as in to the upper indicating line on the gauge... or does pegged=12 o'clock position? Is it true that the entire outdrive needs to be removed to replace these switches? and that they have to be done in pairs? I've also noticed that the trim limiter switch is working in the up/out direction (i.e. it cuts power to the trim when it reaches the upper limit before requiring the "trailer" trim switch), but not in the down/in position (i.e. when trimming down, it'll just keep going, so you have to listen for when the tone of the trim changes to know when to let go)... is that normal? Or should it be limiting in the down/in direction as well?
