    Good Day All,
    My name is Jerry I have been jet boating the rivers in northern Alberta for about 30 years now. I started out using an outboard as the lakes here are small, and who wants to go around in circles all day long anyways. I sold that boat and decided to get into a jet driven boat. The first jet boat I bought was an old converted vee drive. It didn't handle very well,was slow,and wouldn't stop porposing. I took all the guts out of it, and scrapped the hull. I the bought a used Cougar bubble deck race hull (fiberglass). I transferred all the parts I had in it and went river boating. It had a 350 that was done up a little bit, I made my own headers, (couldn't afford to buy any), and pretty much drove the snot out of it for years. It was fairly fast, considering it only had maybe 360 h.p., and it was reliable and good on gas. I sold this, and bought an aluminum race hull in 1989. I put together a turbo charged 350 for it. This thing was awesome. It made 21 lbs. boost, and I estimated it at 700 Horsepower. It would turn an A2 impellor at 5600. Top seed was 92 mph. This was very good in those days. That engine proved to be costly to maintain, and wore out quite quickly (even though it was built from new parts). I rebuilt it, and sold it. I then got into big blocks, starting with a crate iron LS7. It worked alright, but it didn't have quite the speed, (LS7s did not make as much power as they were reputed to make.) I put some Brodix heads on this engine, and that woke it up. Now it was starting to work right. I still have this boat, and I still have this engine. I think of it as old faithful, because it never broke- ever. I have always maintained this machine meticulously, and I am quite proud of it. Over the years, the kids have grown up, and have their own careers, so my wife and I have pretty good incomes. I decided to build myself a new engine, and sell off old faithful. I freshened it up, it should be good for many years yet. It has almost no wear, makes awesome power (600-dynoed), not too heavy, good engine all around. Now, I am building an all aluminum 540, with 12.5:1 compression, and mechanical fuel injection. We shall see how it works , and how reliable it will be. It is sure more costly than any previous engine. Everything starts at $500.00 and goes up from there. By the way, I do all my own work, engine, electrical, r & d, painting, fabricating. I take pride that I am skillful enough to be able to do this work, and it all looks and works professional. Cheers
