I have a weird issue with my Dual control trim. Both of the independent trim switches work fine, both up and down. When I use the switch for both engines, both go up, but the port engine does not go down. I have to use the independent switch. I have checked all of the connections and cleaned...
How is the rev limiter wired on a 4 cylinder 115? I cant seem to find a wiring diagram that shows it anywhere and the only place I can even find the part number is on the BLOCK part number diagram from mercury. Nothing in electrical. Any idea?
I picked up a decent 1996 Mercury 115 2+2 that has the carbs off and was missing a few part. The carbs turned out to be very dirty and 125 castings with the wrong jets in them. The compression is 136 to 140 in all holes. The previous owner says the case halves were sealed with the wrong...
I have a 1996 Mercury 75 3 cylinder. Last week the lower unit failed in catastrophic style.
I am contemplating rebuilding or replacing. This brings up a few questions. I have a 3 jaw reverse gear which seems to be much more expensive to find parts than a 6 jaw unit.
Can I put 6 jaw gears...
I have a 1996 Mariner 3 cylinder 2 stroke 75 Horse outboard. It was running rough land backfired a few times from being lean so I rebuilt the carbs and fuel pump. After that I found a bad reed on #2 cylinder. I replaced all of the reeds with Chris Carson Fiberglass units. I did notice that...
I have a 96 Mariner that I just rebuilt the carbs and set base timing. Before the build I know I had cylinder #2 but it was intermittent. I know the carbs are good, and its getting fuel, I think its getting spark because the timing light flashes in #2 and compression is right at 125 in all...
I just rebuilt the carbs on my 3 cyclinder 75 horse Mariner. One thing I notice, there was nothing in the location that the service manual calls for the Bowl Vent Jet. It is the hole by the idle needle.
None of the carbs had anything in that hole.
Am I missing somthing or is this only in...
I have an older 1996 Mariner outboard that have good compression but has sat for a while and has a few cosmetic issues. Since these motors tend to burn up pistons if once carb leans out, I plan on rebuilding the carbs this weekend and doing a full lync and sync. Once its running well, I will...
I have a 1996 3 cylinder Mariner 75 that the swivel is rusted and stiff. I have been told it is easer to replace the entire mid stection rather than try to replace the Swivel Pin (#99661A35) and bottom yoke (#42961A06) has anyone tried either repair? I found a used mid for about $375. What...
How many pencil annodes are in the power heads of the 3.1 L Yamaha OX66 SWS II 225's?
I found one on the Port side of the block, and one at the bottom of each cycinder head. Is this all of them? Or am I missing some?
I have a recently acquired 1999 Pursuit 2870 Center Console with twin Yamaha 225 OX66 Saltwater II two stroke outboards. Currently the boat has Yamaha Stainless 3-blade 15 1/4" x 19" propellers (Left and right hand rotation). Per the manual, my engines should have a WOT between 4500-5500 rpm...
I have just aquired a pair of 99 Saltwater OX66 225's on my new to me Pursuit 2870. The engines have 698 and 700 hours on them. The boat has been sitting for a while but I filled both tanks (118 gallons EACH :facepalm:) added 1 oz per 10 gallons of ring free and ran her. Both engines have been...
I am new to the area. We just moved into a place on the Imperial River this Sunday. So far have have been to the inlet at Wiggens pass. Where are some other good places to play in the area?
I just picked up a new to me boat. Its a 99 2870 Pursuit with twin 225s. I have only had mercruiser power before now so these are going to be a whole new world. I have a few Questions
#1 Is a service manual and Owners Manual available online?
#2 I was told that I cold use any TC-W3 2 stroke...
