I have owned a 2006 Merry Fisher 655 for the past 3 years.
The boat is fitted with a Volvo Penta D3 110 which I have to say has not performed particularly well insofar as it has developed several faults since I have owned the boat, the latest of which has proved to be the most serious.
The engine has just over 400 hours on it.
I moor the boat at Yachthaven in Plymouth.
Two weeks ago there was international power boat racing in Plymouth Sound. On the Sunday, racing started at 1115. I was anxious to avoid any contact with the event , and was steaming at 14 knots out through the Sound at 1105, my intention being to go wreck fishing in The Channel.
I was two thirds the way out when a large Princess came in at speed past the Breakwater , obviously wanting to return to its berth before the racing started.
The wake from the Princess was enormous and in consequence I reduced speed to 5 knots . When the wake hit me , the boat was thrown all over the place. When it finally passed , I opened up the throttle again and within a second or two the engine died and refused to start.
I was only 30 yards from the shore rocks as the racing course took up most of the Sound , and was very lucky to get a tow back to my berth.
At first I thought there was a fuel flow problem as the fuel level in the pre fuel filter was low. The message on the EVC display however read " Electrical system failure. Service required soon."
The local Volvo Penta agent subsequently attended , and it appears that the fuel injection pump has failed, with no fuel being delivered to the common rail, and in consequence none to the injectors.
A new pump has been ordered ( £1500 -------ouch ! ). The original style pump as fitted to my boat has been superseded by an updated version. Does this mean that the version I have has proved unreliable ? Anyone know ?
What I fail to understand is just how being thrown about by a violent wake could have caused the pump to fail, or is it related to me reducing the throttle very quickly to reduce speed.
Anyone any ideas ?
Volvo Paul, are you still involved with this forum ?
