Same engine testing all of these?
Are you sure all of these are all measuring correctly? When I purchased my American Turbine A impeller it actually ended up measuring closer to A+ so I wouldn't...
Np, Just remember that cutting down your impeller means you'll have to put more foot into it when cruising, towing, skiing, etc so you may want to thing twice about cutting it way down. My impeller...
Unfortunately there are a lot of variables here. Big HP to one and means something completely different to another. For example "big HP" (for a jet boat) in my mind is up over 1000 HP. The engine...
If your impeller was measured and was a true A and your pump was tight then it would take you around 700 HP to spin that RPM. If you cut it down to a B that should give you a 200 to 300 RPM...
Yep, thats my boat in the avatar. When i got it, there was no engine and it needed alot of work. I fully disassembled it and started from scratch doing everything I could myself. The engine is a...
When you post, there is a button above the box where you write, it looks kind of like a picture frame and when you hover over it, it says "Insert Image" click that, then click the browse and select...
Here's an impeller RPM to HP chart for berk impellers

A 12JG pump is good, there are better pumps but you only need to go that route when making serious power. The A stands for the cut impeller that was originally in the pump. A is an aggressive cut...
You need to find out what impeller is in it and what cut. The 12je pump is not the ideal pump for a performance deal but at the same time it doesn't sound like your cavitating the pump which means...
Rick,
3000-3500 RPM is cruising rpm for me, your definitely not even close to waking that engine up. Who did the pump work, do you know what impeller they put in the boat? I would check a couple...
Were you running a forged piston? Ideally forged is the way to go, JE/SRP pistons should work fine. I used them in my last build, i'm using Mahle now just because i got a good deal on them. CP...
There is an event going on this weekend in Parker. Races down at blue water and a regatta at pirates.
Thanksgiving weekend they will be racing at blue water again, this time it will be the circle...
I wish i would have grabbed a full backup of the site back then, we could have had all those pics! At the time I was only concerned about downloading the forum content. Kicking myself in the ass...
Seams like it would be up to the purchaser at the time the boat was made but your right, most outboards are right hand drive. Whats the transom look like? How thick is it? Pull the drain plug out,...
These seam to be pretty unique boats, and it doesn't sound like too many of them where made! Just about every one of them I've seen so far seams to have a different bottom on it. I love the look of...
Forgot to add, use grade8 bolts! Yes they will rust, but stainless is not strong enough around the head. You'll just need to replace them every few years.
Not sure what Jack is charging these days for loaders. I want to say the price is close though, you'll have to call him and see. The advantage would be that jack would help you choose the right...
Loaders take the place of the stock rock grate on your pump. The rock grate is mounted using 2 bolts but with a loader you need to mount them using 4 bolts. 2 of the holes can be reused from where...
There you go! Old Rigger knows his stuff!
76 Hondo, Nice boat! Interesting setup there with the cav plates!
You have any pictures of what they look like?
Rex Marine (www.rexmar.com) has a ton of stuff and they should be able to help you. If it's the old morse steering cable I do not believe you can get them anymore. I had the same problem and just...
my buddy has that same hull, i'll ask him if his says anything.
Looks like a Tahiti to me, what other information are you looking for?
Welcome to the forums! Got any pics of your boats? Post em up if you do!
