Mercruiser not getting rpms
Last time I took the boat out 2 weeks ago it ran like a champ. Today
it wouldnt run over 1800 rpms. Talking about a 1990 merc 5.7 260hp -
alpha one drive. The boat starts and idles great. In throttle only it
revs as high as I dare but put it in gear and 1800 max. I think the
ditributor is good with good timing and no wires crossed. The throttle
body has full movement and peering down the carb looked like it was
wide open. The boat wasnt used much last year and of course sat all
winter. Just wondering what you would look at first?
I could get much higher rpms in reverse but probably due to the prop
taking less of a bite of water.
Any body had something similar??
Thanks
Joel
