The owner of the house where I dock my boat has a 2002 parker with the diesel I/O package and a Bravo 3 out drive. It is the 25' walkaround model.
Two years ago the temp was running high and he was told that there was barnacle and snail growth in the 5/8 ID hose in the drive assembly along with the hose thru the transom mount.
The engine is fresh water cooled with a raw water pump on the engine to cool the heat exchanger, exhaust manifolds and risers. well the engine is starting to run on the high side again..
My question is. Should he install a thru hull to the raw water pump and do away with the pickup in the drive? Will this alteration void the 5 year extended warranty? Or are there additionional things that need to be done to correct the inherent problem?
I have my boat at the same dock and have a Bravo 1 drive with a 5.7 Merccruiser which is all raw water cooled and have had no problems.
Any help or advice will be greatly appreciated.
Thanks in advance.
