Try to get in touch with Achris- he went through a whole ordeal with similar leak was the pan and or cover had for lack of better terms a bump or mismatch that wouldn't allow it to seal properly. He may save you some headaches...
The grey tach wire will go to the negative side of the coil. I assume someone removed it because tach was shorting out the ignition. If you have no spark it is one of the first troubleshooting steps.
As mentioned nothing wrong with a properly maintained points system, its as good as an...
As AD outlined they make longer harnesses both in Merc and universal fit. I think looking at a place like Michigan Motorz and on ebay you would find what you need.
You should put eyes on your existing donor harness, even though the boat is shorter the harness may be long enough for your new...
Yeah agreed heard a lot a bad stuff on fram but ran them on many of my cars for many years and miles… but also changed 3 k on conventional oil and 5-6 k on synthetic…
Trim up only lifts the drive about halfway up. This is the limit of trim you can use during running at speed. Trailer button is used to get all the way up engine shouldn’t be used more than just above idle rpm when in trailer .
there is a limit switch on port side of outdrive that limits how far...
What year is your boat. Older mc-1 had three buttons on the dash. Later ones (my ‘90 alpa one did) had them on shift lever. Suspect someone repowered or added a newer shift lever… may take a little looking around to see whats hooked up …or what someone did…
This is the brass fitting that threads into the 1/" npt female port and adapts to the blue plastic plug. I just bought two to replace the ones on my block sides, you can google the PN to find other sources. Only donw side I see if you ever had debris in there it does restrict the opening a bit...
Not really, see below
exactly water gets in gimbal bearing and needle bearings in ujoints , rusts input shaft causing a leak… may work now but let that moisture corrode the bearings over the winter and it wont work next year.
Leave it alone until you do bellows. you can squeeze up in there and get them but i think you will wish you left it alone before you get done with the job.
there is a youtube video out there of someone who does it without removing bellows ifyou search for it
would pressure test your drive to...
So it is more rpm related than I have it at WOT but am at 4k rpm and accelerating ? If so then I would think you are tapping the rev limiter. I am a life long motor head and it surprised me the first time I hit it on my 21 ft'er w/5.0.
If you see it at lower RPMs when under full throttle...
My thoughts- not sure who is giving you this advice of 100 hp gains and 60 hp gains doesn't seem to now what rpm a marine carb runs at. Seems like salesmanship more so than sound mechanical advice...
What 800 cfm carb is recommended - Jimbo has a 650 on his 5.7 that would essentially be the...
91 is the change over year between gen one and two. My 91 boat was a gen one as the driveline was a 1990 manufacture
