I ran a 650 on a 55H unit with no problems. I would build a simple engine stand using the mid section and water tube without the lower unit and drive shaft. Run the engine up and check for vibration....

That last foot or so of rocker will do it every time. I have seen as little as 1/32" of an inch rocker cause a porpoise such as you describe. Not only uncomfortable but can be unsafe. Turn the boat...

@my guess is about 34 mph, @ 100% not much pitch and no rrrrr,s @2.9:1 Lucky to get 30mph on a boat Rod

Okay, so the CORS can run--now how about the rest of the rules as to course, length, pit stops, fueling etc. Where to be found??? Does the Mini Enduro have a web site? Entry Fees? Contact sources?

Rules for the mini enduro--where can a complete set be found. Length of race, pit stops, course, classes, dates etc???COR boats fit in a class--10 boats ready to go???

Walt, You are correct, it did not like to turn, it liked to hook in a turn! That is the reason we made the changes to the #9 boat. Once changes were made, end of problem, boat ran very well. ...

As I recall, the rev limiter was set at 6725 for the Parker Enduro. The 8 cylinders sounded really great at that rpm. It must have been really sweet when running 20 mph or so faster. I have a much...

The Eliminator Daytona was a beautifule boat and it ran and handled very well after we worked until 3 A.M. in the morning "non-tripping" the chine on the left picklefork and adding a non-skid fin to...

Avgas definitely stores better than auto pump gas. I fly aircraft and also race boats in a class called COR (Classic Outboard Runabout). The engines we run start out as 150 hp V-6 Mercs. In race...

Some boats were built with a hook in the bottom=(I have heard that the coast guard grades a boat on how quickly the nose will drop when the boat is coming up on plane --obviously tied to visibility...

There is a gentleman in the Chicago area called the "foot doctor". Rod

6500 rrr's, no slip, go up 2 inches, same diameter--S/S Ron Hill cleaver. 3blade--stop the chinewalk by simply "tweaking" the wheel towards the side that is lifting, most likely the chine walk starts...

If you are turning 6000 rrrr's now, (with a stock aluminum prop), I think I would go with a SS cleaver of the same pitch and diameter. You have to start somewhere and after trying it, you may find...

Those are great looking units! Great paint jobs. Hope they work out well. Did the 3 cyl blocks "bolt" right up to the Mk 55 mids? Rod

The trim tabs are probably the way to go. What about mounting them just an inch above the bottom, in that manner they would only touch if the bow tries to come up? By the way, that is a good looking...

a couple of additions such as "whales tales" bolted to the cav plate will assist the boat getting on plane. They are used extensively on small/short "blow" (rubber dinghies) boats. Once on plane,...

see my answer below****

The GPS only tells you the speed you are doing over the earth, ground etc. If you are running downstream with a current of 10 mph, your GPS will include the speed of the current plus the speed that...

Thanks for the "eye opener" . I would have never guessed! Rod

Pull the spark plugs after a good run and a quick shut-down. If the plugs are a nice chocolate brown, leave everything alone. If they are a grey-white, better open the high speed jets up a little...

It is still a good thing to check the plugs soon after you have made changes to the carburetion, ignition etc. By checking the plugs you will see exactly how the engine is running in the combustion...

Trim, prop height,weight, balance and prop are the most import items when trying to increase speed of a specific boat. I would think of the two (trim and hydraulic jack), that trim is by far the more...

Will the 5 cylinder fit on your mid-section? I could probably get it reeeeal cheap plus shipping of course.

Is that a 4 or a 5 cylinder engine. There used to be a 5 cyl parts motor around the corner from me. Rod

125 Force was a Chrysler, which was a West Bend and they didn't change much. I don't think you could compare them to either a V-4 or the inline 6.In the 80's they were heavy engines, didn't have a...

D-44, this is a picture of my Curtis Craft on a poster for one of our Key West races. I think I bought it in 1965 and I am thinking I bought it used for 400 bucks. Could this have been your boat? The...

I had and still have a SD/E Curtis Craft I bought in Miami around 1965. I raced this boat in Key West Florida while in the Navy around 1965/66. There was a sister boat called the "Paper Tiger" that...

I have a "line" on a mold for the Sleekcraft SST (outboard). I have been told the mold is "up to speed", on wheels, straight as the day it was built and could be used with only a scrub down and a...

First of all, you don't use bondo on anypart of the boat--bondo absorbs water. Second, you are going to join your ply woo using a plane, chisel and sander. You are going to make all of your joints so...

joining two peices of plywood together to make a longer peice is called "scarfing". If you get on the internet and look up "scarfing plywood" or "Butt-joints and scarfing plywood" it will tell you...

I have no idea what your plans look like nor do I know if your plans are for a 3 point tunnel type hydro, a single step hydro or a straight bottom hydro, with non-trip chines, or trip chines,...

J hydros are a class of boat for beginners, around the age of 9. When they first started they were very simple boats powered by a 5 hp engine. As racing goes and with the advent of 3 point hydros,...

I know that there will be some boat racers in Indiana, I just don't know of any. If you would call APBA(American Power boat Assoc. ==Detroit, Mi.) ask for Gloria, tell her your problem and I...

First mistake, you spent 40 bucks before you were ready to get started, 40 bucks is a cheap mistake, don't compound this mistake by continuing down the wrong road. You may be able to cut your losses...

Present J hydros donot have much buoyancy. In fact most of them have to be hand cranked (rope started) by an assistant while the driver leans well forward to keep the boat balanced and the water from...

OK speed can be a lot of different things to a lot of different people. That 9.8 might get you to 30-32 mph if it is set up right. You may want to think twice before starting on a J hydro. You are...

It is with a great deal of sadness that I received news of TOM DOIDGE passing over the bridge today. Chuck, his oldest son, called me and I immediately sensed the sadness in his voice. It had to be...

Hi Fred, We have started a Classic Outboard Runabout Class (COR) of racing boats out here in California. We have already established the COR 2.0 class and have started work on a COR-100 class,...

Sorry Bill. my Curtis Craft very much resembles the Avitar of 850cc racer. No tunnel, just a vee bottom with a pad. :) Rod

I have a 14 foot vee bottom that I raced as an OPC Family E boat in the 60's. That is when OPC stood for Outboard Pleasure Craft. This boat was known as a Curtis Craft, made in Miami, Fla. The sister...

There is also a bar in Redondo Beach called the "Bull Pen" and if the one in Brawley is anything like the one in Redondo Beach, it will be a lot of fun! and why would you go to Miami during the...

It appears there are three engines standing against the white back drop. The one to the left seems to be a 2 cyl Mercury from the early 50's. Could be a 7 1/2 hp merc rocket or hurricane or it could...

Speaking of Revolution's, how's it going? I have a Revolution on order, for about a year now. If this ever happens, I will also have a HST available--doesn't seem like there is a shortage of boats...

Steve, had I known it was your birthday I would have bought you a beer. Happy Birthday--you are catching up to me, there was a day that I was twice as old as you. Rod:D

Johnny, I don't know about the Fyreman or JSR, but your name never even came to my mind. With your pedigree, why should it. You have always been known for your honest engine work and clean driving,...

ROSS HAS SPOKEN! Stars and Stripes will run as a Div. VI boat if he decides to run, but don't dispare Jim--We will all work together to "build" you a legal COR-2.0 for a minimum cost for our future...

My suggestion to you has always been to discuss your problem with Ross. This is his race, he is "daboss". Actually, I would also like to run in Div.I because I certainly am not running anywhere near...

within reason

Just bring it to the race and hope for two things !) All of the players in Div.III are willing to let you run that "big bore" Suzuki" in their class with their tiny carbs and 120 cu. inch engines, ...

just keep plugg'n!
