Randy,
I did replace the kinked fuel line, I built the carb myself though this is not first one I've done, it didn't make one RPM difference, I installed a new fuel pump - whether its working to spec or not I don't know. I need to do a fuel pressure check. The plugs and the ignition system is all new except for the wires, I think the temp is too warm too. It is a raw water system. I'm beginning to think the tranny is my problem. It was full of water at one time. I've cleaned and washed and have gotten the fluid clear but I 'm wondering if the pressure relief valve is working. Would that let pressure build without bypassing and cause the engine to have to work harder? I've disconnected the throttle linkage and manually opened it. No change. The gas tanks may eventually be the culprit. I ran gas from a clean, portable tank but blew a trim tab cyl before I could get it on plane but it didn't seem to be better at all.
I blew a trans seal so its coming out of the water so I can replace it and the trim tab.

If I pull the trans with it still in the water, will water leak through the shaft?

lets be honest - im sure you have replaced all plugs and wires so that should put that out of the question - 2nd you should replace the tanks, only because those are bad news to begin with - i have a 68 26' and it gets up to the same rpm, but runs perfectly fine through it and mine is made of solid WOOD!!! my opinion is .... once you have replaced all fuel related lines and neccesitties and tanks and yet it still doesnt run the way you think that it should, maybe you should consider the fact that the "old classic" boat that you have (as i have) cant make it to the par that you desire - i mean ours has had everything possible done and it still runs at 30 to 35 mph wide open and has 55 mph on the 40 yr old speedometer. these old boys weren't meant to rock the wake - from what you have said at this point, if you are lookin for more speed and finesse across open water, ............... go newer because the oldies weren't there yet -----------my 2 cents

Patrick,
Its not speed I'm looking for. It's a properly operating drive train.
At its current rate the boat is not safe nor operational.
I'm planning on replacing the tanks. We are taking measurements this morning and tying to figure out how to get the old ones out.

You should be able to get the tank (you are saying "tanks" but I think you only have one by the transom) out via access panel removal on the cockpit deck. It's screwed down. You should have a couple of other smaller ones, but there is a large one on the cockpit deck.....of course, I'm talking about my 77 F-26 with a fiberglass cockpit. Hope we're talking apples and apples here.

Randy,
I've got two. One on either side. Looks like they took two tanks and built a boat around them!! They'll come out though..one way or the other.

low speed/rpm's

If you plan to take the boat out of the water, check the propeller pitch and diameter. I have been following this thread and I had a similar problem when I bought an old 26' pace maker w/ no engine. If the pitch is too much it will bog down the engine (like trying to drive your car in 4th gear all the time). I may be wrong but keep your mind open to other possibilities than just fuel. Eliminate each on as you go.

Thanks John,
That is on my list of things to check. My marina does not have any extra stands to dry dock the boat and I don't have a trailer. A friend is letting me borrow his but not until he brings it back from Florida in two weeks. I'll be able to tell a lot more about it then. This has gone from troublesome to frustrating to a challenge to just plain head-scratchin' funny now!
