Thank you in advance.
i have a 20' 1997 Blue Water Open Bow Ski boat powered by a Volvo 5.7 GLI FLKDCU attached to an SX drive 19* 4 blade Alum Solas prop. With the current set up the boat has given us 3 years of fun for my sons and myself. Last summer the engine started to cut out around 2600 rpm's suddenly and the boat wouldn't plane. I was informed by the local marine repair/dealership that my High Pressure pump was most likely the issue because it was whining and "warmer than usual". Replaces it, no questions asked. I get it back on the water, and the same thing happens AGAIN!! So I follow their guidance and replace the Low pressure fuel pump and the filter. Now were are a couple hundred bucks later and today I take her out. She ran great for about 30 min then I lost all power above 2500 rpms. She just falls flat on her face. Power literally cuts out like it is a fuel problem. Luckily (insert sarcasm here) I happen to have a Volvo mechanic come floating on by and he offer his $.02 and we were both thinking it makes sense that one of the exhaust Flappers could come loose/broken off and be covering the "Y" pipe before the bellows directs the exhaust out to the stern drive , because both elbows were warmer than usual. So with high hopes, I come home, pull the elbows and both flappers are properly secured. I even took a piece of hose and push it through to see if there were any obstructions on either side. There is nothing that I can figure out.
New Fuel Filter from Napa.
New Volvo HP Fuel pump
New Volvo LP Fuel Pump.
New Impeller for cooling system
Oil changed every season of 100 hours (which ever comes first)
All annual/seasonal maintenance is done.
Please, I am boggled beyond belief... :grumpy:
