Engine for Dyno Jet?

Postby twier » Thu Feb 09, 2017 3:15 pm

Does anyone have an opinion on using the Rotax 900 ACE engine (60 hp, 4 cycle) out of a Sea Doo Spark in a Dyno Jet?

Thanks in advance.

Hi Twier.

I didn't delve too far into the Spark powertrain when I set the specs for my TNT, but from what I gathered during my research, I think it would work great for a Dynojet build.
Light weight and being a shorter setup lengthwise (depending on how the drive is set up), the Spark powertrain should lend itself well in a stich-n-glue setup, which doesn't offer the ability to stretch the hull.
Being a very efficient and, from what I've read, a very reliable engine are definitely nice bonuses.

A very big thumbs up from me. I'd love to see how a package like this would perform! :D

Thanks
Dave

Thanks for the reply Dave. I think the next step is to go look at one and measure the drive train to make sure it will fit.
