My new project - 86 - 272 LS

befu,
been following this thread because the 272 is the direction I want to go in.
Anyway its too bad you've had so much bad luck after all the work you've done but you'll get passed it.
My one question, why the heck would you run one fuel pump on a twin? Go to 2 fuel pumps please!!! Or at least carry a spare, its a silly reason to be dead in the water in a twin engine boat.
Good luck and I'll continue to follow, I want to see a top speed number!!!

I went with one fuel pump to simplify it. Cars have one and run for thousands of hours without a problem, with a lowest cost eom also. Thought a Holley would be better and with its spec flow, should have been plenty. Obviously not and after being stranded twice by it, I will have new ones and in duplicate next spring. Now that I have at least ran it a couple of times, I am more willing to start spending money n it again.
Oh, and by next summer it will fit our family again. By then our four foster children will be moved on, hopefully back to family so we will be down to just our five children! nothing like trying to finish a boat during summer that all the kids would not fit on.

Don't worry about the dust, mine was pretty dang dirty this summer even after a few preliminary cleanings!

Brian...I'm going to say I think the lake water was cold and it just took a while to warm those engines up enough to burn off the condensation moisture.
You are making me feel bad with those old Q-Jets. If I can find a good pair of Holley 750 DP's I'll send you my good Q-Jets. Don't worry about the $$...just send me what they are worth to you if they work out.

It is odd how that motor dried itself out after we fixed the intake manifold. I am curious if the intake let loose again or if it was something else. We will get it pulled, do a compression check on it and then open it up. At the minimum it is going to need a gasket set and I will put in new bearings.
Thanks.

Thanks, let me look at my second temp gauge, it is the only thing not working right now. If I can get it to work, I think I will keep them. Keep us posted on your dash. I want to make a new dash cabinet for mine this winter. You just redoing the panel inserts or are you changing around the whole housing?
Then the autometers which are platinum face chrome bezels. All toggle switches will be white with white military rockers for trim. On passenger side panel above glove box it has 272 sr1 on it now. That will be put back like it is by airbrush and in center of that panel will be I.C.U. Lookin' airbrushed in same font as 272 sr1. (Wife is an icu nurse).

befu,
call me crazy, but when I built my motor I just went with a summit electric fuel pump, if i remember it was like 80 bucks or so. I have NEVER had any trouble with it, 125+hrs (knocking on wood right now). At the time I just thought it would hold me over, but why change. I free flow tested it at about 80 gallons per hour. I don't know who actually makes it but it must not be holly because it actually works!! I hit 67.5 in my 206 a couple weekends ago, cold weather and low fuel. I had about 1.5 mph of current so it was an honest 66. Have a good winter

Engine update
Went out and looked at the motors. Once things had a chance to cool and settle down, doesn't look as bad as I originally thought.
the Port motor was coughing pretty bad. Not back firing, but more of a "popping". Wasn't good as the oil in the bilge looks like it came from this motor. Feeling along the bottom of the timing chain cover, there is oil there. so, if a motor is popping like that, can it over pressurize the crankcase and push oil out the front seals? Wondering if it was the gas I put in it on the way to the lake. That popping was new on this run. I am guessing it was only the port motor that was popping like that from the sound of it. Maybe the other motor was doing it also, just not as loud? Anyways, the oil looks fine in that motor, just a 1/2 quart low.
the Starboard motor is pretty much a complete repeat of the first time it took on water. Oil level is about 1/4 to 1/2 quart high and has the brown water look to it. didn't cook it real bad as the water seperated out floating on top. Oil looked clean when we checked it the next morning. Then we did a compression check on the motor and it read at 150 psi on all the cylinders. Checking the oil again, it was stirred up and you could see the brown. so water in it, but must not of been in long. so we will pull it out and pull bearings for inspection/replacement.
On the SB motor we will do a pressure check on the motor cooling system. If the intake manifold is leaking again, we will pull it and inspect further. Maybe I got a bad intake manifold that is not sealing properly?
I thought I remembered seeing the SB motor with more foam on top of it, but we were drifting at that point, so not sure. I thought there was a lot of oil in the bilge also, but there was only some water with oil floating on top, just looked really dirty.
either way, got work to do now. Here is a picture of the SB motor with some of the settled foam that dripped off the cold flame arrestor onto the manifold and the oil in the bilge.
