Hello.
I have a 1999 Regal Commodore 242 fitted with a Mercruiser 5.0 EFI.
The issue is when first setting off, I can get the boat to around 30mph. Then as time goes by, say 10 minutes, it'll top out at 25mph. Skip forward another 10 minutes it'll top out at 20mph and so on. It will get it a point where it won't go beyond 10mph if that at full throttle. The engine just bogs down. With very fast throttle input the engine nearly dies. I have to apply the throttle slowly?
So far under the mechanics advice I have had it serviced (including new rotor arm and distributor cap, antifoul, new fuel pump, new batteries) and yet the issue still persists. They believe it is a fuel issue, perhaps the fuel pressure slowly dies off but the mechanic at this point isn't interested anymore as he can't scam more money out of me for stuff that isn't causing the issue.
What does your experience tell you guys?
