Have a 1987 Eddtide Rivera 18 ft w/ OMC Cobra 4.3L. Have replaced the lower unit with a brand new one from SEI. It was very difficult removing pulling shaft out.
Same with installing, but got it in.
Started up the boat cranked up in a couple of tries. Idle is at 600 rpm, runs very smooth at idle. Just fueled up, was empty. Use Premium fuel.
Shifted into forward, engine begins to spurt and begins to run very rough and stalls. Tried a few time and did engage a couple of times and began running rough then kicked on ran very well,No clunking going into gear, very smooth shifting.
Shifted into reverse and shifts very smooth, no noise or clunking runs great.
Added gear lube, changed oil, oil filter, checked fuel filter looks very clean. Fuel filter in Carb is bronze, looks very clean
All this was done on trailer with muffs
Before changing lower unit boat ran like a dream. Easy start up, shifting great, throttled up great.
What am I missing or what should I do?
