Just purchased a 3.0l for my 87 Stingray. I have everything together, except the wiring. I have a new harness I am going to put in tomorrow. The motor came w/ the distribution already on, I transferred over the motor mount and bell housing, updated 12.75 inch fly wheel and coupler. I guess my...
After 29 years of minimum repairs I finally needed an engine rebuild. The cost to rebuild outweighed the cost to buy a new one. I bought a new one from Doug Russel marina (local to me). So with the motor I was told I needed to purchase:
- starter
- newer style flywheel
- coupler
- exhaust...
Can someone tell me what the difference is between a pre-1999 and post 1999 thermostat housing for a merc 3.0? Other than the 90 degree inlet for the transom hose, I'm not sure what the difference is. They use the same gasket and mounting. I purchased a new base 3.0 engine and curious if I could...
I built a gentry crane from HD w/ some 4x4's 10 feet tall, 9 feet wide with a 1 ton chain fall. I have everything disconnected and going to pull the engine tomorrow. Should I disconnect the front motor mount by pulling out the lag screws out of the stringer or disconnect the motor mount from the...
Thanks, I can't do the adjustment while its running because I can't get to start again. It just backfires and smokes out of the spark arrestor.
I believe the firing order is correct, it's been connected the same way for the past 29 years. I've attached a picture to show how its connected. Each...
I did a valve adjustment on my 87 3.0l today and the boat would not start after I did the adjustment. I followed the instructions from mercruiser manual #10. I marked the distributor at one and turned the engine by hand until the rotor pointed to cylinder 1 with the point gap open then made the...
I purchased a new carb from http://flyingfishcarburetors.com/ (mercarb sn: 1389-9350) for my 87 Stingray, 3.0l as its been about 10 years since I've had it rebuilt. Up until then the boat ran great. While waiting for the carb to come in I replaced the thermostat. New carb comes in, put it on...
So I noticed when I replaced my circulation pump on my 87 3.0 theres 4 holes for the bolts and another small hole that the water pump body fits over. Can anyone tell me the purpose of this? It was a little clogged and I cleaned it out and put some compressed air down there and it did shoot...
I replace my upper oil seal every year when i do the impeller as peace of mind . I take the old one out w/ a screwdriver. To install the one I went to HD, bought a 12 inch piece of threaded rod 3 fender washes and 2 nuts. I sandwiched the washers between the 2 nuts at the very end of the rod...
This is my first post here but I've been creeping as a non-member on here for years and always seem to find the right answers/advice I'm looking for- so thank you in advance, everyone.
So, I recently replaced the carb on my 1987 (Stingray SVB 176 SS). I've owned the boat forever and always...
