Volvo 5.0 Gxi break-in

[mlpaskett]

I have a new boat with the Volvo 5.0Gxi for power. I am closely following the break-in procedures found in the owner's manual. With just over 4 hours on engine, I have run it up to WOT a few times reaching about 4500 rpm. The manual and Volvo's web site indicate that the WOT rpm should be about 5000 rpm. I once read somewhere (can't remember where) that the engine doesn't come into its full horsepower potential until 20 or 30 hours of run time. Is this true or am I currently over-propped? While running at WOT and hitting about 4500 rpm, the speedo reads 50 - 53 mph so performance seems pretty good. What do you think?

Thanks,

Mark

Probably over propped, you should really be talking to your dealer about this right now.

Thanks Don. Dealer went out of business 3 weeks after purchase in October. Was just wondering if I should chase down another dealer for Volvo service etc.

You will probably have to eat the price of a set of props, those are normally part of the boat dealers setup to make sure the right props are on a particular boat, not Volvo. but you really don't want to be overpropped during breakin.
