Evinrude 28 Special lower unit
 

Hello,

I have a nephew with a Evinrude 28 hp outboard about '98 model which
seems to have a lower unit problem??? It runs well at idle speed or
trolling speed but when the throttle is raised the motor revs up but
the boat does not speed up accordingly??? There is no grinding or
otherwise bad sounding noise noticeable. He has checked the lower
unit lube condition and it was fine. He also removed the prop but
found nothing noticeably wrong. He has not misused the boat/motor.
The prop is not even nicked. Any ideas as to what could be wrong
inside this thing?

Thanks for any help or info........

Most likely the rubber hub inside the prop is "spun" and slipping since
there are no noises or clunks when the motor is accelerated. Try a different
prop and I'll bet things will be fine. Some prop shops can replace the hub,
but on that small sized prop, a new one may be a better value.
