    1984 Merc 75hp low top speed

    I've got an 84 75 up Mercury outboard on a 16 ft mirrocraft from the 60s to 70s, closed bow with a console. The outboard seems to run alright, but this combo is going a top speed of 31 mph on flat water, with just me and fuel onboard. I'm suspicious of a few things with this boat. Just bought...

    93 Johnson 15 hp trouble running

    I just bought a boat with this 15 hp Johnson outboard on it, and I believe its starving for fuel. I started it up in my driveway with water muffs, and it started second pull like usual. After it started, it died and wouldn't restart. The primer bulb was hard, but no fuel sprayed when I...

    58' Evinrude Big Twin rebuild.

    I've decided that I'm going to do a basic rebuild on my 58" Evinrude Big Twin 35 hp. I have a few issues with it, and instead of trying to chase them all down, I figure I may as well just make it "new". Can anybody help me out with a parts list for this? I'm afraid I'll leave something out.

    58' Evinrude Big Twin overheating.

    It has water flow. Get that out of the way first. The thing ran like a champ when I put it in the water. After fishing for a while, I played around a bit with the boat. I was adjusting the trim to see which one was right and I would run at WOT between adjustments. It appeared to be getting...

    Water intrusion on cuffs.

    I just replaced the gear oil in my 58' Evinrude Big Twin 35 HP and ran the motor on cuffs while trying to find another problem. I took the top oil screw out to check the oil because there was some oil coming out of the water bypass cover. The oil which had been filled to about 1/16" below the...

    58' Evinrude Big Twin Fuel tank issues?

    When I got this motor, it ran well on the tank it came with. The tank is one of the Cruise-a-day pressure tanks. I took the motor home and wanted to put it on my cuffs (which I'm glad to say, do work on this motor, unlike my other outboard) and make sure I was good to go for a fishing trip...

    Fuel Tank 58' Evinrude Big Twin

    I left the pressure tank for my Big twin in the shed and forgot to crack the cap and release pressure. It was hot that day. When I went back into the shed, the tank had leaked some fuel. The thing is, the tank holds pressure and runs the outboard perfectly. Is this just a pressure release...

    35 HP Evinrude Prop.

    I have a 35 HP Evinrude that has the appearance of the paint on the prop being removed by cavitation or something like that. It has a small say 1/4" long crack in one of the blades. Would I be able to keep this as a spare?

    Electric Starter for 71' Rude 25 hp

    My friend has a 25 HP 71' evinrude and he wants to put electric start on it. I have seen these outboards with electric start before, but I can't find a starter for it. Anybody know where to get one? He has bad shoulders and so it's hard for him to start his outboard.

    Which prop sounds right.

    I have a 14 ft fiberglass boat, generally loaded with two 20 pound anchors, 2 life jackets, 6 gallons of gas, 2 rather small individuals (one is about 100 pounds the other weighs about 140), a small cooler full of drinks, fishing tackle, and that's pretty much it. I have a Johnson 9.5 HP...

    67' 9.5 will not idle, and is running hot.

    My little 9.5 still will not idle. The motor is now running hot. Not severely, but it will burn me if I touch the head. It is pumping water. I had the low speed screw backed out an entire 14 turns after initial adjustment. No improvement. It runs perfectly at WOT, and runs mildly better...

    66' Mercury 3.9 hp no spark.

    Okay, so this motor has no spark. What kind of ignition do these run and where should I start diagnosing the issue? I unfortunately, do not have a manual.

    66' Mercury 3.9 hp not peeing, impeller is fine.

    Okay, so it runs, but there is no water coming from the pee hole. The impeller is new, anybody have any suggestions? Maybe the parts diagram and water circulation diagram? Figure maybe it's just plugged up.

    67' 9.5 has trouble.

    Okay, so I thought that I had fixed the problem with my motor. I went out fishing yesterday. That was an outing I'll tell ya. Anyway, the lake was getting a bit choppy, and I had been trolling all day, and my engine just decides to die. Now, while trolling, the engine would idle smoothly...

    Cleaning low speed jets in a 67' Johnson 9.5

    This is probably not new to some, but it was quite a discovery for me. I had my carb disassembled for a rebuild, and I couldn't figure out how to get at the three small orifices under the butterfly valve to clean them. Well, I looked and looked and it seemed the only way to get to them was to...

    67' 9.5 with trouble idling.

    I have already changed the spark plugs, breaker points and condensers, and removed and cleaned the carburator. The engine will not run at an idle of less than about 1200 rpm. It will for a minute, but then it will rock as one of the cylinders misfires, then will eventually die. I did a...

    Replacing head gasket? 67' 9.5

    The previous owner of this engine had the head off of this motor at one time, and didn't put a new one on. So, I am going to replace the head gasket. Can I do this without removing the entire power head? Seems like I could easily just remove the head, replace the gasket, inspect and retorque.

    Not sure what to look for, water flow.

    I have a 67' 9.5 horsepower Johnson, and when running in my water container, it sprays water out of the back, underneath the engine. Thing is, it sprays, it's not a stream. Seems like so long as water is above the anti cavitation plate, it sprays. But if it's below it, it doesn't. Sprays the...

    Flywheel nut torque.

    67' Johnson 9.5 horse. According to the Clymer manual I have, I either torque it to 40-45 ft-lbs, or 100. But, the thing is, I can't tell which one it is. Any help?

    Questions about my boat trailer.

    So, I have a 12' fiberglass boat with a 9.5 hp Johnson. The trailer that it came on confuses me. I was always under the impression that bunks were intended to support the weight of the boat, but it seems this trailer uses the bunks to center it, and some rollers to support it. What do you...
