I'd check or replace lower unit grease. What are your RPM's at idle? Might be too high.

I've always smeared a little marine grease on those things to prevent this. I've also had to purchase and use starter shims on outboard starters before.

Yeah, possibly an adjustment on both ends of cable?

The primer bulb fills up the bowls of the carburetor. If your needle and seat aren't working properly, you'll actually pump gas beyond the needle and seat and flood the motor. The best way to test for a flooded motor is to open the throttle up to half or even full throttle and pull the rope...

If you have access to an air compressor, I'd blow out all the fuel lines starting at motor and blowing toward the tank. Also, need to check the vent hose. Also, if one section of hose has deteriorated, you may have the same problem between the tank and filter. Also check the screen on the...

I used to fight and bust knuckles on rusted bolts all the time. I now have 3' lengths of 1/2", 3/4" and 1" galvanized pipe that can slide over all of my different sized breaker bars. I'm in my 60's now, so I've decided to work smarter! I know that with serious rust and corrosion, sometimes a...

Airshot suggested that he check the throttle cable while motor is running. He told OP to remove the shift cable before testing, but I think OP overlooked that step.

I just Googled "1984 35 HP Mercury Outboard" Just slightly over 4,000,000 results. Time to shop!! Not hard to find parts online.

What did you set the gap at? 3/8" or even 7/16" is a good indication of a strong spark.

My 9 year old granddaughter asked me to take her tubing today. Great fun! I dropped everything to take her and my son out in the boat. Boat ran great, but on 3 occasions while I was running at about 2000 RPM's to go pick her up or just to make it through no wake zones, the overheat alarm went...

Absolutely you can.

What problems were you having before the carb adjustment? How is it running? What are your RPMs? When will you be taking back to this mechanic to tell him about the new problem?

If you supply the model number of the motor, we can tell you more about the shifting mechanism. Not all motors have a shift shaft that moves up/down, many have a shift shaft that turns. If the shift shaft isn't going up/down, look for the connection from the cable hookup to see if something...

I'm not an inboard/outboard guy, but that knocking is definitely a valve knock. Either like someone suggested above the rocker stud has worked loose, lifter has gone bad, or for some reason a valve is not opening on that cylinder. I'd certainly remove the valve cover to look for issues before...

I can't speak for Mercury outboards, but I've had 2 Yamaha outboards that have had the floats in the oil tanks go bad and cause the alarm to go off indicating low/no oil in tank. On Yamaha, there is a tank on the motor and an auxiliary tank mounted somewhere else that feeds the tank on the...

The only solution I can come up with is like you say take the cowling off, turn prime system on, start and let warm up, turn primer system off (so it doesn't run too rich), put the cowling back on and go. Or, you could run wires to a switch on the console to turn the primer system on and off...

I guess I've not been doing a good job keeping the cover on my boat. The gauges have gotten all cloudy and I can't read them any more. They're the OEM 2 round gauge set. Does anyone have a set laying around that they're not using that they would like to sell or trade something for them? I've...

Thanks for backing me up guys. I was the lone ranger there for a while. It could also be a lighted switch wired incorrectly. A switch that has a light that comes on when the switch is turned on basically has 2 circuits and at least 3 wires. Hot, ground and load (power to the light in this...

Yeah, I was pretty sure that motor had 2 relays. My son recently had to replace the entire system on his 115 Johnson. The sockets for the relays were worn out and became very "iffy" only working sometimes. That first wiring diagram has a mistake. I've always told folks when working with...

I watched that video too. My son has the same motor, but his is a 2003TLRB. the "B" is used on year models where there is a significant change from previous models. That change in 2003 included that priming system. It's a pretty neat concept, but my son just started having problems with cold...
