3rd engine is in...your prayers please...Lol

[shockerfd]

Well, the third and final engine installment is done. Their is fresh fuel mixed at 32:1 along with SBT's break-in oil. The cooling and fuel lines are blown out and clear. The carbs have been gone through once again and hopefully all is well. A new throttle cable and rotary valve cover have been installed also. The boat sounded great on land and is set to specs. It will probably be the weekend before I get to drop it in the water. Cross your fingers and pray this one will run great for me. Way too much time and money have been spent on this boat and it owes me! My family and I would like to enjoy the boat this summer.

Just a quick thanks to Karl for the deal on the throttle cable and to Snipe for his technical insight and willingness to go the extra mile for me if I need it.

Hey shocker , hows it going on that 3rd engine? Get it figured out?

I had to put a new one in mine this year and have not got it out yet for break in., are you using your oil injections on that or just premix?
I ended up replacing the fuel valve because it was restricting fuel causing a lean condition.
I had simular problems like you with my boat.
Also do you know how much gas a quart of SBT break in oil treats?
I had about 3 inches of gas in my tank and the mechanic added a full quart to that and now I need to know how much gas to add. Any ideas on that?
Thanks.

Kind of so far so good. I'm trying to figure out a fuel issue with the carbs. If I can get that worked out, I think I'm in the clear. (knocks on wood and prays)I will say between talking to members on this forum and swapping out 3 engines, I have gained valuable information on this boat. I am doing the premix and cautiously going through the break-in procedure. With any 2 stroke, its not a bad idea going with a little richer than usual mixture with break in. Spark plugs are much cheaper than engines. If you don't already know, its important to keep doing constant plug checks to see how the engine is running.

I have also found other little issues with this engine set up that the previous owner left. I don't even know how it ran at all the first time. Come to think of it, it didn't run long. There were cooling lines reversed along with fuel lines from the tank baffle that were not where they were supposed to be.

Good luck and be patient and smart with your break-in.

With my 787 SBT last year, everytime I filled up the gas tank I would add about....5 seconds worth of oil in to the tank. I am going to do the same this year....as well as keep the oil tank filled.

This is how I broke my engine in though....

The morning of boating I open my storage bay to let the condensation start to dry up. Fill up, fill it up with a couple seconds worth of oil, any extra oil is just going to get burned off anyways. This being a 2 banger...

30 minutes of dinking around basically doing nothing, varying my rpms in 2-3k.

Turn it off for 15-30 minutes Let it cool. Start it back up, and do another 30 minutes of 2-4k rpm driving.

I don't know how long I did this for, SBT says to do it for a certain period of time, but it certainly doesn't hurt to do it for a little longer. I know you need 10 hours on it, and hopefully warm waters (60 degrees or above) before you can feel comfortable flying around.

My engine did overheat on me during break in a few times, about 6-7 hours in to break in I just couldn't wait to lay on it and I would kick it in to 6000rpm and cruise varying my rpm's.

This whole engine on / off thing is very annoying, and I find myself bored as hell watching other boats go by while I sit and let my engine cool off lol.

My engine is going in this week, hope to have my boat back by Wednesday / Thursday. I want to get out on the water and have the engine broke in by coast guard festival for when things get a lil crazy around here.

Are you breaking in another engine?

I know all about sitting and waiting but the patience will be worth it. After 3 engines, I can take my time. The 6 year old isn't too happy with the starts and stops but I try my best to explain to her why. I was in the back of the boat tinkering this weekend and had a couple of boaters stop by to check in. Glad to know people were looking out.

I know the feeling on that one,LOL My 6 year old is ready to get out there it's drivin him nuts, lol kid is fearless and gets bored easy, a trick keepin him entertaimed. Got this boat basically for him and mom , chompin at the bit to get out on the water. He sits in the boat " when we goin dad?"
Soon I say. When? But when? When???????? !@#$% #

Here is how I broke my engine in basically....

During the first 10 gallons of gasoline, there should be NO full throttle operation. First idle the engine for about 10 minutes to ensure that the engine is properly warmed-up. Then begin varying the throttle position up and down, up to 20% throttle for a half hour. Then come back and let the engine cool off completely - it should be a good 30 min break. After it cools down, you may now ride it up to 50% throttle for another half hour or so. Then come back again and let it completely cool down again. Now you can go out and ride up to 90% throttle. Continue this for the remainder of the 10 gallons, never holding one throttle position for more than a few seconds. Do not run at a steady throttle position and do not go to 100% throttle. After your first tank of gas, replace your plugs with fresh ones. For the second tank, you may ride normally with one exception - do not hold it at 100% throttle for more than a few seconds. After the second tank of gas, you are completely broken in and may ride anyway you like.

Do not worry my friends. I will mow through many tanks of gasoline before Coast Guard festival.....I will be out from sun up to sun down / when I don't work :rant:

Oh this form here officially makes me feel like a retard not doing the engine work myself. It's like here is a picture guided instructional manual and you can't even do that?

 

[WaveShredder9110]

I'll definitly do the job next time myself , screw the fees for labor , and then your at the mercy as when they can get to it.
The guy I brought mine to , told me 10 days, on the 9th day I called to see how he was coming on it and he told me he just got the sbt motor the day before I called.
I almost came UNGLUED!!!
Like , what the hell you been doing for 8 days????
Then gives me a guilt trip as "I had to work the whole weekend on it"
Un-frickin-real.
Never again do pay to have someone just swap motors. NOT!!!!

The first engine swap took most of the day to remove the old one, install new one and rebuild the carbs. This being the third engine swap took a few hours. It's not bad at all. Take your time, follow the directions and you'll save money and get the satisfaction of doing it yourself, not to mention a much more understanding of how this boat works. I found a lot of little things wrong with this boat in the downtime waiting for this last engine to arrive.
