Awesome I will do that once I fire up the motor next. How long would you think it would take for that color to appear on the plugs? Pretty quick or do I need to run the motor a couple hours? Glad to hear my fuel consumption is typical.

Okay well that's good to know. I had no idea this was a symptom of tri-hulls. I'll have to do more research on them so I know what to expect. It is very stable. It not a big boat but two people can stand on one side of the boat and it won't tip much at all. How about fuel economy? By my math I...

Jiggz, I will look into getting some kind of foam perhaps. Thats good info of the plugs too. I was curious if these were wrong. I went to a marine supply and bought what they said my motor needed. Wouldn't be surprised if they were wrong so I'll order the proper plugs. As for the air/fuel...

Okay cool, all be sure to check the reeds for certain too.

Okay sweet I'll take a look at them. May be a while, I keep my boat on my family property halfway across the state. I don't have space where I live so I'll have to look when I go there next. If the motor sucked in foam past the reeds, will it just burn it up run out the exhaust? Or is it going...

Any way to inspect/clean the reeds?

Here's a tiny clip of the boat at max throttle. The butterfly only opens to about 80-90 % and I just adjusted the throttle linkage so I think that's the best I can do. Does the bow look a little low? This is at my fasted trim setting.

here are the plugs. Left is top, right is bottom. Of course now they look the exact same in the photo, but the piston heads where certainly different colors.

Hey everyone, So I finally got my force out on the water for the first time this season. For context, it's a fixer upper. I just rebuilt the fuel pump and this sucker fired up without even the throttle advance after sitting for 8 months. I was excited. Anyway, on the test run I did 14 miles in...

As of today my 15ft tri-hull got 24 mph with two people. I don't have the motor running top notch and I've been told my boat is a slug so I guess that's not so bad.

Took the boat out today and the gauge worked great. My motor hovered between 110 and 135 the whole time. Still needs some finer tuning on the motor performance side of things but I'm happy I don't have to wonder if my motor is burning up a piston while I cruise to the fishing grounds.

Got the temp gauge installed. Works pretty good I think. Motor seems to sit rat at 100 degrees at idle. I'll see how hot it gets while running today.

Pumps nice cold water too. Just started to decarb as well. Nice to see it work now. I'm sure a proper carb and pump kit and this motor will really purr.

The float seems to float well. It's a hollow plastic type. Looks level as well. Gave the carb another good cleaning. I couldn't get a hold of a pump kit near me so I have to order one. In the mean time, I took some lubricant and moistened the pump diaphragm which gave it some playability back...

Yeah I wasn't sure how bad it really was, but I have another motor I'm working on that does have bad diaphragm and when I compared this old one to the other motors new one then I could tell.

Okay, I guess I was refering to an initial air mix screw setting, but I'm gonna pull the carb again and do a deeper clean. The fuel pump is marginal too. The diaphragm is a little crispy. I'll double check the fuel bowl again. I know the float needle looked new

So I got the motor hooked up to fuel and water. Fires up but doesn't idle for long at all. What's a good carb setting? My initial thought is it's a carb adjustment issue.

That's a good idea I still have the ones they sent me. I'll see if they actually sent me the right ones. I noticed when I bought them off cowley, when I click on the mariner model, it automatically sends me to the equal model Yamaha. Maybe that has something to do with it. Better find some more...
