YOUR OPINION,? 32' 9'' Eliminator Daytona with Twin Evinrude V-8's,

[300x Stoker]

Is it true that the V'8s hold about a bathtub full of water so don't forget to figure that minor detail. Don't they take a few minutes to start peeing????????? Although dry weights are similar my suspicion is that the 3L Merc is a lighter running package. Sorry for off topic. My inquiring mind would like to know?

[tunnelfun]

Captain's 23 is a full weight hull as factory shipped boat. He's running healthy 390 horse Evolution V8's with Evolution light twelve pound cowls. Twelve inches of setback. Transom pickups. One 80 pound k-plane on center pod, not needed and should be removed. The bottom has the usual 23 design flaws with no abnormal hook/rocker defects out of common for a 23. Dry boat with no evidence of rot or water log.
The labbed by somebody 14 1/2 x 32 Mazco three blade clevers are not hooking up. 94 mph @ 7800 rpm's and climbing at shut down (overrev fear) with 1.62 gear. Excess trim needed for top speed. Does not respond to motor elevation changes. Full throttle planning at all reasonable motor trim settings with k-plane full up is instantaneous with no excessive prop slip. Acceleration is very impressive, as expected.
Boat was never dialed in, no attempt made after 1991.
Has anyone ever seen a twin V8 23 dialed in? Help hookup a great fellow boater.

That is good looking boat. It looks like the exhaust have plugs in them? Are you running the motors with them in, if so that makes a difference if there making 390 hp it should be open. I remember talking to Ron Baker and said the one he had ran 110 with twin V8's.

I believe Captain's would be interested in ANY info available for his boat.

@ 7800 rpm's

No way I would have spun my Stage V Evo V8's 7800. At 7200, they were all done, and those were the 430hp versions. When I went to the Monty V8's, I kept stock limiters (6700) to keep the reliability.

Any issues in the midrange with those motors? I assume they are Stage IV's? Mine would NOT run from 3500-4400 due to porting. If you got them to 3500, they jumped to 4400, and if you let them get just below 4400, they bogged to 3500.

Excess trim needed for top speed.

It does sound like more bow lift is needed despite all that mass far behind the transom.

I would try whatever bow lifting props I could lay my hands on, ideally working from the extremes, e.g. Mazco RE4s if they even come in a lefty version.

Yes many rpm's. That's why the test termination. No porting issues. Pulls like a bull from idle on up. Stage four's, many $.

I believe Captain's will spend some money on props before dial in comes around. I've suggested he remove the two 90 pound full sheets of 3/4 inch plywood floor with glass on both sides from the dash bulkhead forward.
Does anyone in Wisconsin have prop's for testing. 15x34's, 36's?

[HydroSkreamin]

I saw this boat at a shop in Omro, WI on my way home tonight.

Captain, you still own this?

I guess I should have clarified that I meant you could not cruise between 3500-4400. In my boat, that jump meant I had to be going under 35mph or over 48mph...could not cruise between there. Full throttle, they pulled through no issue.

Yikes besides looking awsum that is a ton on the back of that 23 I saw one years ago think Steve quick looked like it was sinking at idle

[tunnelfun]

No. No part throttle hole in the power curve. Ran 4000 rpm just fine.

Must be one of the differences between a Stage IV and Stage V.

[QUOTE=Brad Zastrow;3050839]Those 23's are not that heavy and the last thing he needs with the big outboards is bow lift. Run three blade cleavers 14.5 diameter with a pitch to be determined.[/QUOTE


Agreed. My 24 ran best with 30x 14.5 4 blade cleavers. Top end was 32x14.5 3 blade cleavers. My two cents!

[JPEROG]

Hello Brad, I'll work on getting you more information, prop size,pitch,and rpm, Check out the small Fountain I used to have, It sat really low in the water too, So low that people would think I didn't put the drain plug in and the boat was sinking, It had twin big blocks in it, Attachment 409821

Had the same boat. Mine was an 89' with twin 365 magnums. Moved up to a 35 lightning "same exact colors" and my wife didn't realize I had made a change for 3 months lol....
