Hi
I bought the boat last year - a 640 C Bar Crusher when it was fitted with a Solas 14.25 X 17 X 3 prop. It seemed way under propped.
As a result I bought a Power Tech 4 blade which has made a huge difference. Only thing is that WOT is at the bottom (about 5200 rpm) of the recommended range in the Honda manual which is 5000 - 6000 rpm.
The rev counter is analogue so not exactly sure of accuracy.
Got the following results with GPS when testing both props.
The Honda seems to run very easily at between 4000 - 4500 rpm - the V boost kicks in at about 4300 rpm - with the Power Tech. The table shows the results. Am I likely to damage the engine by persisting with the 4 blade Power Tech prop?
Regards
Neville
