I wasnt thinking pull start
Well, neither was I but it was the first dressed powerhead picture I could find. Anyway, if you imagine the pull start being out of those pictures, I'm really thinking about all the stuff BRP hung low on the sides, taking advantage of additional space in the lower side covers of the Etec. I think a 45SS lower pan would limit space for those hoses, oil tank, and other wiring that hangs down on the sides of the Etec powerhead. Again, I'm not against this idea at all, simply pointing out possible issues.
One thing that came to mind with the E-tec blocks is whether or not the oiling locations from the oil injection are strategic in the design in such a way were you NEED to oil those locations in a particular way. The worry is that premix may not lubricate those locations properly..? Has anyone inspected these details? Or can we assume it'd be ok to run pre-mix only?
The Seaway version
I just looked on the bench, the top of the lifting eyes are at the same height,
So I will need to find a crank and flywheel to check if my guess was right or not?
The top of the etec block at the crank is higher than the 45 block but about 1/2" so will depend on the flywheel.
The 2 cylinder ETEC has a massive tower and inside that tower is a tuned exhaust. The exhaust goes down and wraps back up giving a single cylinder tuned length.
If you put it on another tower you're going to lose that tuning and a lot of power, and of course you'll need to retune the fuel injection to make sure you get a good mixture without the tuned exhaust.
