This seems to be a VERY COMMON and PERSISTENT and virtually IRRESOLVABLE problem with this product.
The engine starts like a NASA launch and runs well at idle or WOT for about 45 minutes, then begins, what I'll call, tapping/ missing/ sputtering/ spitting at about 20 second intervals that slowly increase over maybe 5 minutes until forward progress is just one long, continuous, jerking heave, the engine then completely fails, and won't restart.
If the boat sits for about an hour before the engine will finally turn over, but the sputter routine begins after just a couple minutes, until it again stalls, and again won't restart.
My local (Volvo certified, 20+ years experience) mechanic is humbled and flummoxed. I've returned it to his shop 6 times in 9 weeks. He's had it on the water 3 times himself to experience the problem first hand. He's replaced, greased, dried, reconfigured, tightened, loosened, abracadabra-d, exorcised, and prayed over all of the obvious first-to-fail systems, pieces, and parts (coil, condenser, plugs, wiring, deadman switch, exhaust manifold, compression, filters, pumps).
This boat is my personal, real life B-O-A-T joke. I'm $$ replacing, fixing parts that aren't broken.
Of course, there's always the possibility that some bad part has been replaced with a bad part.
This, as I say, from what I glean from internet boat forums, is a LONG-COMMON problem. Certainly someone has stumbled on a solution. Anyone?
One additional symptom, related/ relevant? who knows. I sometimes get, almost always get at first WOT, say 4000+ RPMs a metallic-like whir or wheezing. Back off the throttle and it goes away.
Your thoughts, please.
