Fred,

Replacing the tiller arm requires a LOT of wrench turning with an "acetylene wrench" on many seized bolts, so don't blame you for considering a repower. There's a good reason that BRP made that part out of SS on the E-TEC's!

Those BRP 115's are probably bullet proof motors, but if you consider the cost of adding dual controls, steering cables, wiring harnesses, instrumentation, batteries, spare props, etc. plus factor in the cost of 2X more maintenance, extra transom weight, and 2X more stuff to go wrong, it might actually be cheaper to look for a late model "plug & play" big single. Plus if it won't plane on one motor, you'd be just as well off from an offshore safety/reliability standpoint with a kicker and a big single! I'd try to stay with a BRP vintage carb'd motor though (2001 or later Johnson), unless you can find a deal on a 2005 or later 3.3L E-TEC! ARG in Riviera Beach often has some good used motors, and their service manager Lenny is a good guy (an ex-coastie!) Denny

Thanks Denny,
Wise Advise as always!
I saw some motors on the ARG website..going to give them a call and see what they can do for me...looks like they have quite the inventory!

Fred- Stay with a single! Twins sound good, but not necessary!! Performance and cost are better with 1 big motor. Get a kicker! I am storing my 4.5 hp motor under my bench seat when I'm out.

I think ARG is selling a lot of E-TEC's, although they also sell Honda and Yamaha . . . saw something on the E-TEC owners website recently which said that, although Yamaha is No. 1 on new boat sales and Merc is No. 2, the E-TEC is No. 1 in repower sales, so they're evidently replacing a lot of 4-strokes! ARG takes in a lot of motors that way.

Fred,
If you decide to go with the twins, I have some dual OMC tachs, trim indicator guages and the engine connector rod that came off a 76 SC 23 center console setup. The 23 had dual 1996 115's Evinrudes. Unfortunately, I just sold the dual top mount controls, harnesses, cables and ignitions switches.

Plagarism!!! I single handedly invented the 90% underpowered non-planing offshore deep vee!!!! But if you are serious about this Seanoe then make sure use dual counte-rotating weed wackers so ensure proper tracking.
