I just got the same engine and I haven’t gone through it yet. I plan to this week but the person that sold it to me said they were having trouble getting it started but when they did, it would run OK but then bog out they said that they were having to spray gas into the carb throat so they assume That it’s a carb float hopefully in the next week or so I’ll get it taken apart great video btw
Sup man, i have an identical outboard and I’m having some troubles with finding parts. So I have two questions. 1 where did you find the blue print for it? And 2 where did you find those spark plugs? Loved the video btw 👍😁
Just bought one of these engines, been told it turns over an thats it, bought it blind and should be delivered early next week so I may be I touch 😂 nice vid tho ma man
I just got a Thunderbolt. Holy bjeezus, it's fast. Before 1985 Carl K. from mercury under-rated his outboards so they would out-sell the other brands. Then the government changed the dyno testing regulations in '84 or '85. So the '9.8' Thunderbolt dynos at least 12 hp.
gasket number 6 and number 21 are needed as well as 20. if you look at the bottom center they have two nipples kinda. these actually help pump fuel into and stop fuel from backing out. ther number twenty is a pass through without the flappers. there are manuals online or find a merc or clymer manual. if the gaskets were there before thewn they need to stay there.
So a word of advice to you...NEVER EVER spray starting fluid of ANY brand into ANY 2 stroke engine EVER. That's the best way to wash out any cylinder oil and cause piston/cylinder wall scoring! Especially since you just loosened up that engine from being seized. Instead...mix up some oil/gas mix and use a spray bottle to shoot some into the card directly that way these is still lubricant going thru the motor. And if you think the plugs are too wet to fire, pull them out and spray some carb/parts cleaner on them and reinstall. You're way better off doing it this way... Just some friendly advice.
Thanks for the advice! I was recommended that after I made the video but I will start doing that now that I know. I was using carb cleaner instead of starting fluid but I will use 2 stroke gas mix next time thank you
My Arctic cat 900 cc doesn't like to start cold and they don't have a primer. So to prime it I use my premixed Ethanol free, very definitely a good idea.
I have the same engine and I am searching for a part or part number, hopefully someone can help. The smaller hose from the carburetor goes back into the engine through an elbow. The elbow is brass and I believe it is a 3/8" threaded male on one end and an 1/8" id hose barb on the other, and also has a built in screen. I broke the damaged hose barb completely off. Does anyone know where I can get that elbow?. Thanks
Are you sure you are supposed to stack those gaskets? I "think" they are showing 3 gasket options in that position for different situations. I don't think you are supposed to use all of them. I've never heard of stacking gaskets before.
