Gas or 2-stroke inboards

Struggling to find a small (approx 50-80hp) inboard engine for a new design. Note that Rotax only supply to Seadoo, Weber are too tall for the application and Yamaha do a small 2-stroke engine but for competition only i.e. fails on emissions. Any thoughts would be appreciated, noting that I don't really want to buy a jet-ski to strip down.

Is this for a single project or are you going into production?

 

Its a custom tender; i.e. a one off.

 

The Bombardier/Seadoo dealer won't sell you a power package? They normally have replacements for Seadoos.

 

I'm just getting the dims from a local dealer, but they are not too happy to supply - although if it is the right height..... I suspect it will be too tall however as they are all based around the 1500 4-stroke ie. 130HP plus...

 

Mercury Marine only makes the 200 and 250 models any more.

 

What type of gear, wheel, shaft setup do you desire? Are you thinking jet? I don't have any suggestions at this point but I am curious.

 

Jet. Investigating pwc technology but even these engines seem a little tall and powerful for the proposed application.

 

Look at the ROTAX and HURTH engines made for ultra lightaircraft .

Most are air cooled , but some are water cooled.

Almost all are 2 stroke and really light. Most have 1000 hours before overhaul.

BRP/Rotax have a current 2 cyl E Tec ( emission rated) water cooled engine in one model ski doo

 

Thank you folks... I think we have a way forward starting with a Yam 2-stroke 2-cyl if we can get around the emissions issue or possibly a Seadoo (rotax) if we can convince those who supply that we are not in competition with their brand. Many thanks again.
