vapor lock

Have had the boat on out Lake Erie 5 times now. Other than our first voyage where we discovered the coil was shot and got towed back, the 5.7 Merc has run great. Temp dead on at 170. Easily cruising at 25-30. Have some things left to do still. But my biggest issue is vapor lock at this...

So I am finally going to install fuel boost pumps on my twin 4.3MPI engines to hopefully once and for all fix my vapor lock problems I've had over the years. My simple question is...for those that have them installed on their 280DA (or similar twin engine Sea Ray), where is the boost pump and...

And so, the saga continues... Over the last couple of years I've been battling vapor lock in my twin 4.3MPI's. I've gotten better about dealing with it and preventing it but in some circumstances it's hard to avoid a scenario that will make it happen (re-fueling at a fuel dock, fishing). Over...

Last weekend the temp was in the low 90's. We ran for 30+ miles most of the time at around 3200 RPM. Stopped a couple of times for a few minutes then off and running again. No problems. In fact the boat (280DA Sundancer T-4.3 MPI Alpha) is running great. We found a quiet cove and fired up...
