" I have twin 95 mariners 135hp that both seem to be running at half power WOT is only 4000 rpm
and have a hard time getting on plane. But when on idle will rev up to 5000 rpm.The engines are not running hot.
Replaced fuel filters at motors, replaced racor fuel water seperators and the sight glass tells me they are getting fuel. it acts like the powerpack is bad. but on both motors???? they idle rough. checked for loose grounds.
Is there an hi or lo governor or something electronically that could have gone bad and utilizes only 3 cyls instead of 6??
hope somebody can give me a sequence to trouble shoot with a DVM
Txs in advance "
