Major engine help!
 

MY 206 seems destroyed to me in my eyes...I jsut finished installing my new long block 350 everything was going great until I went to start it...no fuel so me being an idoit instead of priming the right way I pour somr fuel into the carb...well to describe what happened I have never heard of before. It sounded like a shotgun went off in the back of my boat...the worst backfire ever on the planet...it cracked the fiberglass on my platform and almost completly blew it off. my cell phone that was on it shot up about 10 feet in the air...my question is 2 parted

what the hell can I do about this plaform now as the upper hooks are where the damage is..

and what happened to the motor...i knew it wasnt' timed perfectly but I thought it was close, I have been off 180 before and havent experienced this...so give it to me straight what are you thoughts to what happened. was it the feul into the carb or the timing? and how bad is the damage..

ps carb has fuel now :-(

sounds like you have there silent thunder exaust ? you must of had raw fuel in the platform/exaust and then your backfire ignited it . scary stuff

how could that have happened? is it from when I put it in the carb...is that what would happen if poured it past the jets?

You indicate you knew better...
 

You're 180 out or your counter rotating your standard rotator.

To prevent damage in the future from this kind of backfire, why not try this instead:

This test will determine if you are spinning the motor in the opposite direction as a result of installing an incorrect starter.

1. Remove thru hull exhaust, leaving risers exposed
2. Pour about 3 cups of water into each exhaust manifold
3. Attempt to start engine
4. Watch water come out of carburator

Kick self in ass, for doing things the hard way !!!

The starter is the same from the old motor...so i am assuming its turning the right way...or is there a way that its not?? also i will be taking pictures of the platform today!

I would recheck your timing. I bet you are 180 degrees off.
Pull the plug off No. Put your finger in the hole. When its starts the comression stroke (you will know) bring it up to TDC and install.

ok so update:

Got motor started without platform. The distributor was out 180(like many of you said)...One would just assume that when the engine manufacturer send you the engine, it would be in the correct TDC well now the engine sounds a bit loud one one side I am hoping it just an exhaust leak and will be changing it out tomorrow. (fingers crossed)Maybe the whole motor hasn't gotten oil yet since it has only ran for about 30 seconds


Does anyone know what size tip I have to get now that I will be running without the platform for a bit? I still haven't taken the old tips yet...that looks like FUN! will post the pics of the platform later!

Hold on a minute cowboy , the motor hasn't gotten oil yet? You should have primed the oil pump before you installed the distributor! I take the valve covers off and while priming the oil pump I make sure there is oil coming out of every pushrod!

Looks like I'll have to do that as well...Shouldn't the engine manufacturer have already done that...Precision Engine is the builder.

Never assume. Call to see if they did. If not and you ran it, could cause damage. If all you did was crank it, that's ok.
