Re: Tsunami/bracket power options
 

My Sceptre-to-Savage project is up at G-Crafts with Bobby now. I was thinking about a stainless marine bracket with twin 115 4 stroke Yamahas. Top end in the high 30's will be fine with me. Yamaha's web site shows performance data on a 23'6' Sailfish with twin 115's. the "sweatspot" is 4000 rpms, 26 mph, 9.5 gpm and 2.85 mpg. Whats wrong with that??

Took my other 23 Sceptre to the Georgetown Hole last Friday. burned 110 gal with the old 225 Suzuki 2 stroke. Total trip distance on the gps was 156 s-miles (including trolling). 5 nice dolphin and wahoo (first trip in the boat)

This discussion has me thinking about twin 150's but just how many days do you meed to go 40 mph offshore??

The twin Hemco bracket is 800+lbs on flotation. I would be interested to see what the flotation is on the ones being built on CSC.

Re: Tsunami/bracket power options
 

I would go with the 150's. There is almost no weight difference 402 vs 466 pounds. The issue isn't so much of speed, but of how hard you work the motors. The 150's would probably last longer, and may get better gas milage at the same speed over water as the 115's. Once any of these motors hit 4000 rpm, they start sucking gas, fast.

I know someone that put twin 115's suzukis on a 23 sceptre, and regreted not going with the 140's.

I am still having problems with the thought of putting over 900 pounds of engine on the back of these 23's. The boats were designed/balanced for 350-450 on the back. Maybe the brackets make it work, but from a balance perspective, I would like to ride/drive one.

Re: Tsunami/bracket power options
 

John-
I agree on balance with twins. It is over the intended weight. Fellowship has good points on that topic. That is my only hang-up with my 890lb twin 225 set-up.

Re: Tsunami/bracket power options
 

Hey JohnB, I'm 90% sure that's my old Sceptre in your post.
If it is, how's it doing?? I sold my 32 and am looking into another Sceptre. The 32 was fun, but I still like the 23 better.

Re: Tsunami/bracket power options
 

Don't worry so much about the weight aft. Don't forget the 23' CC and Sceptre was available new with twin I/O Mercruiser 165 sterndrives, with a combined weight of approx 1200 lbs, and the 23' SeaVette was offered with twin I/O Mercruiser 5.7L V8 260 hp, with a combined weight of 1600 lbs.

What about a Single Diesel or (bracket with a single 250 Suzuki and a yamaha T series kicker) . . . bayracer will sell them for $13K.

It's a LOT less expensive to maintain one motor . . . if you use the kicker for trolling then you don't put the hours on your big motor, you save lots of fuel, and you have redundancy :).

Re: Tsunami/bracket power options
 

Thanks Fr Frank..... I have seen those around on the net....but I didn't know the weight specs. I didn't think there'd be a difference in the inner liner/floor either, but wasn't 100% sure. I'm moving along....progress is pretty slow due to work..... :( But I'm feeling better about the bracket/engine plan.... :D

Re: Tsunami/bracket power options
 

Bigshrimpin,

I remember you busting my chops over buying from Bayracer a couple of years ago...now you are stumping for them!

Re: Tsunami/bracket power options
 

I think BigShrimpin is right. A single driving outboard with a good sized kicker will do the job. AND cost a whole lot less up front and down the road.
