Green river to Moab and back. May 25th
West coast of BC leave Colorado August 10
Yankton SD to Kansas City October- ish

I'm trying to get all my projects done before the first trip of the year

Wag bag style toilet under high deck bench made from aluminum (trash bag and kitty litter when not in a state park that requires an approved method)
Air powered stomp grate
New Garmins, just got this done today
Install new XM weather antenna
Turbo impeller
Hard side windows
Drill out every snap rivet and replace with longer length rivet.
Powder coat trim tabs
Cut out side exhaust and weld side back in
Add hole for anchor winch line to go through
Hold open latches for front doors

That's all I have to do. What modification have you done to your boat that you don't want to live without?

If anybody else would like to join for the green river to Moab run that would be great. The scenery is pretty wild, check it out on google earth. Here is some info on the trip. http://friendshipcruise.com/

How close are you on the Turbo Impeller?

Front impeller now fits over the 2" shaft. Next step build it up to the right OD. Turbo 274 here we come! :Drink:

More machineing done today. If you're thinking about doing this yourself, don't. Send it to Rick...

Here is a 241 impeller in a 274 pump for a visual comparison. I should have the turbo done by the end of the Month.

I'm headed to lake of the ozarks for the Shootout the 25th, who else is going? :boat:

Looks great! Any performance reports/numbers to share yet?

I haven't had the boat in the water yet. Keep running into problems, all minor. This is not a straight forward conversion, lots of machineing to make the puzzle fit together. I think I have it then something else hits and I'm back to the drawing board. Hopefully I can have the boat in the water this week.

83,147 views. wow, that's a lot. Feel free to add to the thread.

Another winter of too much work and not enough work happening on the boat. I never did get the boat on the water to test the turbo impeller, Ill be ready for spring thats for sure!

I've followed this thread for a while and this build is quite impressive. The turbo 274 is a great idea and look forward to seeing those performance numbers.

Was there ever a winner for the top speed guess? If so, what was it? Just curious

I also never saw the final weight of the boat. It always seemed heavier than the numbers thrown out early on. Can you share?
Thanks

Fishbucket- I totally forgot about the top speed guesses. I'll get a number on a the lake as soon as it's not ice.
I think the boat is around 8800lbs. If I ever leave the boat on the water I'll get the trailer down to the scale.

Great job ! Very interest tests your boat. I also made my first welded turbo impeller for my water jet with a BMW diesel engine, in a month we will conduct tests. :Drink:

The turbo impeller was tested today and it was AWESOME!!!! It can take all 570 hp and 1300 lb/ft of torque without even thinking about blowing out. What a difference! I am so happy, couldn't have asked for better results.

Very Cool :Drink: :Drink: How is your top end Rpm? Does it go to top RPM that the engine needs to see? I was sceptical as to wether it would work. Mainly because it did not look like the Turbo would be in the wear ring.

It will bump 3200 rpm, I'm guessing it's at around 12.5kw. I am delivering the impeller to Rick to add some kW and balance it. It amazes me the kW is so close. I'd say about 33% of the front impeller is in the wear ring, the rest is very close (feeler gauge close.)

Lost a couple mph so far (49mph today with strong wind) that I think we can get back with the kW.

What Rpm is that engine supposed to max out at?

It needs to turn 3000 min to be approved by cascade and FPT. 3150 is fuel cut off.

Well done and congratulations! I didn’t think the wear ring would make much difference on the front section since it acts more like an inducer, the incredible part is how close the KW rating is to optimum. Did you have some design algorithms or get lucky?

All luck on this one. It would take some serious software to simulate flow and power consumption. My logic was if the 241 turbo works I can make the 274 turbo work. The turning point for me was when I learned of the 7.5kw turbo 241, at that point I knew I could make it work.

I look forward to finding some white water to test it (I'll have to find some talent for the captain position.)
