The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Whats the most likely scenario for why there would be water in my #6 cyl? Took the motor in for a tune up, had rust on my bottom plug. The boat starts and runs fine, except that it occasionally wants to be "choked" when applying throttle to avoid bogging. One quick tap of the choke button and it...
I have a 1976 16' monarch boat with a 1980 merc 90 on it, I-6. I believe the prop to be a 17" diameter 20 pitch. I recently installed this motor and today was my shakedown cruise. Idle in the water is between 1000-1100 rpms in neutral.
In gear idle seems a bit low, at 500rpms or so, she died a...
1976 mercury 650 type 1 trim...
is the larger of the two trim hoses the up or down hose? Id assume its the larger hose, to allow for easy return flow, but I dont know, hence the question. Thanks!
While running my new (to me) 1980 90hp I-6 on the muffs, water exits above the prop from the holes, as well as from the pee hole. The stream on my 76 650 thunderbolt merc is like a super soaker, whereas this motor is weaker. Is this just characteristic of the bigger motor?
Not my motor, but...
While trying to remove the shock absorbers on my 1980 merc 90, to replace them with the ptt system from my 76 650, I broke the head off of the bolt that goes INTO the lower shock mount pin. I cant get the pin out, and I cant seem to find any information for this online. Anyone have any ideas of...
hello again, more questions for the iboat experts! I'm wondering if my 1980 90hp mercury 6cyl will be able to use the mounting brackets from my 1976 merc. 650? From what I can tell, the brackets are spaced the same distance apart, and the swivel brackets are virtually identical in width. Also...

here's the situation: I'm putting a 1980-81 merc. 90hp 6 cyl. motor (sn 5672259) in place of my 1976 merc 650 65hp motor (sn 4386952) The 65 hp motor has the distributor-less thunderbolt ignition. I'm going to reuse the existing controls, and ignition, because its already installed, and in much...
Im replacing a 76 merc 650 65 hp triple with a 1979/80 merc. 90 hp. Few questions:
Will the power trim/tilt from my 65 fit my 90? its got two rams, two hoses each, that seem to replace the "assist shocks" I really hope so....
Second, My "control box," the nuetral throttle/gearshift, will that...
