    Minimum compression

    My neighbour knows I work on boat motors (Mercury) and he asked me to look at a 1969 Evinrude 9.5 that his father in law owns. He said it would run for a few seconds then stop. He had some shade tree look at it. They replaced the points and condenser (incorrectly gapped) and new plugs. They...

    Bench test rotation sensor?

    I am wondering if you can bench test a rotation sensor for the oil injection system? I thought apply +12V to white wire, ground black wire. Insert + test prob on blue/white and - test prob on ground wire. You should be able to simulate the engine turning by using a strong magnet to the end of...

    Oil alarm on black max

    On my `89 V-135 I am having problems with the alarm going off as soon as the engine starts (pulsing beep). I have checked the float in the upper oil tank and it is fine. No continuity to ground when float is up. I checked for voltage at the white wire going to the speed sensor at the pump...

    1989 Mercury 135

    I am planning on looking at a boat with a 1989 Mercury 135 "blackmax" I have never been around these V6 outboards and know very little about them besides they or atleast the older ones share the same switchboxes and coils as my `80 115 inline six. I also assume this motor is oil injected. Is...

    Updating an `80 Merc 115 trim/tilt

    My `80 115 has the older style two cylinder trim/tilt. I saw in a junk yard a newer 65HP Merc oil injected motor with the trim/tilt built into the transom assembly. Could I remove the powerhead/exhaust housing and use this trim/tilt on my motor? Thanks!

    Performance between a 165 and 888 Mercruiser

    I am wondering if there would be any performance difference between a Mercruiser 165 (inline 6) and a Mercruiser 888 in a 19' closed bow deep V? The reason I ask is because my boat has a rotten transom from a leaking gimbal housing gasket, I gotta pull the engine anyway and thought about...

    greasing newly installed gimbal bearing

    1974 Mercruiser MC1 165. I was installing my new gimbal bearing. Before installing I lined up the space in the tolerance ring with the hole in the outer race. I don't recall seeing if the hole in the outer race lined up with the hole in the bearing, I'm hoping it was, because its brand new...

    1980 GT-150 refurb

    I put some of my other projects on hold (SSV-177) and decided to work on the GT and try to get it finished so I can use it this summer. I knew the boat had a weak transom and the floor wasn't right. It ended up the PO screwed down a piece of 3/4 over the existing floor, making the floor even...

    Starting from scratch Mercury 115 Glastron SSV167

    I've got a newly bought 1980 Glastron SSV-167 with a 1980 Mercury 115 with power trim. The motor didn't come with a prop and I'd like to get a good idea where to start. 16' v bottom boat, weights 850 lbs, 350 lbs motor, 500 to 800 lbs fuel, poeple, and gear. Roughly 1800 lbs. For a prop I'm...

    Eska spark plugs water pump

    Seems like Eska's are pretty popular in this forum! I have a 1973 9.5 and I'm wondering what are the correct spark plugs for this engine? I was wondering if I could use the gap-less plugs my Mercury 7.5 uses? In my reseach is appears the impeller in my `75 Mercury 7.5 will fit the Eska? Thanks!

    1963 Mercury 850

    Quick question, whats the difference between the 850 and 1000 engines? They're both the 90" engines, do the carbs make up the difference, or port sizes? Thanks!

    PA boat registration stickers

    I recently bought another boat about 2 months ago and I finally got my stickers in the mail and realized they changed!!! What happened to the cool keystone stickers? I've always liked the old ones since I was a kid and don't care much for the new ones. What do my fellow PA boaters think?

    `74 engine in a `86 Alpha drive

    I'm starting to put together my engine and drive package and I'm running into a small problem. The 140hp engine from the `86 rig needs a bunch of small things done to it, like front and rear seals, new manifold, oil pan gasket, valve cover gasket. However, my `74 140hp engine is in great...

    Power trim/tilt system

    I was at a friends place looking at mercruiser stuff and found a boat with a merc outboard with a missing power head. By the looks of the lower unit, its a large gear case, tower of power or big 4? I don't know for sure. Anyway, it had the old style of power trim using the two cylinders on...

    Differences in MC1 transom assembly

    My current set up is a 1974 Mercruiser one drive, 140HP. I've been thinking about getting a later transom assembly from a 1979 or so. This would take advantage of the new style trim switches and the current cutout pattern. Would everything else still work from my `74 set up? I'm aware I...

    Merc 500 shift problem

    I'm stilling having an issue with the shifting of my `75 Merc 500. The main problem is it will not "lock" its self into reverse. When you shift into reverse with the control, you can still turn the prop and it won't turn the engine, it will grip, release, turn, grip, ect, both directions...

    Lower unit problems

    I have an `89 Evinrude 40, E40ELCEC and I'm missing all the bolts that hold the lower unit onto the exhaust housing. My motor came dissassembled and I want to bolt on the lower unit I just got so I can run the engine with water. Does anyone know what the correct size of bolts are. SAE or...

    Evinrude 40 hp

    Hello I just bought a GT 150 and it has a 40 hp on the back, model TE40ELCEC, serial number G02335202. I believe its a 1989? It has a damaged lower unit, looks like a tooth came off a gear and got stuck between the gears and the housing, the housing lost. The boat came with a good lower...
