I/O (Sterndrive) Conversion to Outboards

[Pmt133]

Wow . . . you would think they would put their best foot forward. I did talk to someone about a pair of used Suzukis (2021). Both gear cases have been replaced under warranty/recall sort of issues.

I think it is all a crap shoot as to how reliable the engines are (or not).

I agree. Much like anything else at this point you're rolling the dice. It's been 10 years since I've even been to a show so it was nice to check it out again.

I will say I sat down with a formula rep looking at the 33... had twin 400s on the back. He ran them with the older triple setups then with the twins and said the current mercs, even in the twin setup down on power a little, are really impressive. I obviously don't have formula money... but a guy can dream.

This is what's happening for the engines . . .

Honda BF350's AUDA/AUCDA
Optimus 360 Joystick system

They are big, but rarely has it ever been recommended to get a smaller engine when it comes to boats . . .

I just got back from the re-power shop, having placed the order. With the sales incentive, it puts me back in-line with my original budget .

Very nice Ted, 700 hp! And less weight!

Actually these engines are heavy, so the overall weight will come out about the same.

The Suzuki 350 HP would have been 747lbs, the Mercury 350's would have been 720lbs. These Hondas are 776lbs. (each)

 

[Pmt133]

Thought the mercs were under 700... or did they exaggerate a wee bit?

 

[Lou C]

Interesting, so about the same weight as (engine alone) a Mercruiser V8, but then you have to add the transom mount/outdrive and you know how heavy Bravos are lol.

So decided to go with the weight equivalent of the V10 instead of V8

so...... you have to leave 1 case of beer behind? or did you account for that in the buoyancy calculations

Being back on budget must feel real nice.
I can’t say I have ever heard anyone say anything bad about Hondas. I had a 15 back in the 80’s and it was bullet proof and never let me down. They are heavy but in my eyes that usually means better built.
Congratulations

Yes, there is about 2,000 lbs of buoyancy in the extension-bracket. Per the analysis the N.A. did, the hull sits with a very slight positive trim. Between the extra weight of the engines and gear ( I mean beer ), the boat should be around 1˚ positive trim.

To get 350 HP, you have to go to the V10 . . . Top of the V8 line (600 ish lbs) is 300 HP.

Yes, excited about the budget fix . . . I also saved $1,900 by ordering silver instead of white.
