Engine hours on a recreational boat are just that -- the number of hours the engine has been running (meter is connected to ignition in case of gasoline engines, ?? in case of diesels).
I'm not sure I agree with "recreational power boats may be operated over a wide range of RPMs" -- most boats are operated at wide open throttle (except in restricted speed zones or marinas). There are no engines built specifically for recreational boats; instead they are marinarized versions of engines primarily destined for other vehicles -- cars and trucks, for example. Marine engine mechanics will tell you that these engines see rougher service aboard boats, primarily because of the fact that they are usually run flat out.

Apologies all around. Hit send instead of spell check.
Examples below, but to the point are engine hours based on a time clock or rpm?....
A private aircraft is for ....
Recreational power boats may operated over a wide range of speeds/rpm with widely-varying mpg/gpm and related engine wear.
Do "hours" account for this variable?
