Can anybody tell me the correct drum rotor end play fro a CMB67? I have found some old info about this but nothing definitive. I have 4 motors I'm going through and one has .015" and the others are at .023". I haven't measured one without the gasket so I don't know what the minimum would be...

So I need to update my radio system for my fleet. I'm looking at the 4PM but I see its backordered on a lot of sites and out of stock at Futaba. The reason I'm changing is due to the lack of receiver availability for my old fasst system (that is working fine by the way). I want to avoid getting...

Does anyone have a Futaba R603FS receiver they would like to part with? Thx, Brent

Anybody have any tips on reducing launch cavitation on a ABC 2416 prop on a scale hydro? It takes half a lap to get it going then it really flys. If I could get it to work at slow speeds it would be a good prop. Thanks, Brent

Anyone ever look at putting up some kind of barrier across the lake to isolate the race course from the rest of the lake? That way the community could still use the rest of the lake while we race and avoid conflicts between racers and the public.

Anyone know the paint codes for the 1971-72 Pay n Pak? Thanks, Brent

I just bought a new piston and sleeve for my CMB green head and noticed the piston is covered with tiny pits (metal porosity). Is this normal? I have never replaced one before so I'm not sure it they are supposed to be this way. My original one does not have this. Thanks, Brent

Anyone have an old parts list for rotary valve motors? I need to find a number for the rotary disc as it's worn out. I have found a part source but need a number. Thanks, Brent

Anyone have the team radio freq's for this year. i want to program my scanner for this weekend at seafair. Thanks, Brent

Anyone know where I can get a straight (not angled) header for a K&B 67? I'm fitting one into my scale hydro and the angled one won't work with my cowling. Thanks, Brent

I'm starting to get my new Miss Exide dialed in and running pretty good but it' seems to be getting terrible fuel economy. It will burn thrrough 18 oz in a race and if I start it before the clock gets to two minutes it won't finish. The needle is open 3 1/2 turns on the OS9 carb and it puts...

I was watching some old hydro video and noticed the 67 Harrah's Club had an automotive engine mounted in front of the allison. Was that for extra drive shaft power or did it run somekind of blower?? Anybody know about this odd setup? Just curious. Brent

Are there any other players in the game besides the CMB 67? Who is currently selling CMB's now in the USA? Brent

Tomorrow is our first practice day and it's been snowing here all day. More snow predicted tomorrow. What kind of adjustments need to be made to run in the freezing weather? Temp supposed to be 34-38 degrees. Brent :(

Has anyone found a plug that can be left out of the radio box to allow charging the battery without opening the box? I have found several sources on the web but would like to draw on some experience before I collect a bunch of stuff I can't use. The location of the radio in my roundnose is...

Does anyone know how to disable the trim buttons just above your thumb below the steering wheel, grip lever B. I keep inadvertantly bumping it and as a result it changes the steering rate reducing the rudder travel. I don't see anywhere in the manual how disable or reassign the button Thanks...

Does anyone have any pictures of the 1963 Exide (hull 6375) that exploded at the Diamond cup? I have found several black and whites but no good color shots. Most of them are of the wreck or the baot at speed. I need a trailer shot or something static to help detail my new project. Thanks, Brent

It sounds like a lot of round nose boat will be built this winter. I also have got the round nose bug. What are the thought on belly pans? I'm at the point where I need to figure this out. Does the pan help keep the boat on the water or make it more likely to blow over? Thanks, Brent

Before I start working on this comming winters round nose project, I thought I would ask around for the best attributes of a successful 1/8 scale shovel. I'm interested in ride pad design tunnel design and weight distribution or anything to help it stay on the water and perform well. Thanks...
