Rotax Engine Upgrades

Postby Caddellwelding » Sun Mar 06, 2016 3:45 pm

Is there anything a guy can do to a 503 rotax as far as sprucing up the motor? I was asked if this was possible. I've searched it and haven't seen anything.

Contact Rotax Rick. Sorry I don't have his number but I can get it if you need me to.

:shock: Never dealt with him personally but PapaJack has on his boats. Never heard anything bad about him. May PM and get his feedback.

If it is on an air boat then I would say just do the standard power making mods. Is it a 2 stroke? Is it on an air boat?
That article clearly shows the guy never planed the block or head standard stuff for putting a new head gasket on an engine. That's the type of work you should stay away from. :banghead:

I've been to Rotax Rick's shop several times. I never had any issues with the work he did for me. He allowed me to watch as he worked and answered any questions I had. I think the ultralight forums would crucify any work that endangered lives. JMO

I have to re think my first qote after looking at those pictures in that article real good that piston is either old worn out or someone was running their mixture pretty bad. Either way that should not be going on but let me tell you of something I had found years back I owner operated an engine shop for small go kart racing engines had a really great build for a guy wanted the best fastest engine that could be built in his class I spent two weeks on that engine for him to tell me it blew up the third race night? I expected to have that engine run half season at the very least before needing to be freshened up so I brought another engine to the track for him and watched as in between races he changed his oil so I felt confident until I asked him where his old oil was and he showed me how they simply filter the oil and rerun it cause it's not cheap. Jist of the story is there are two sides to everything and if this guy is building junk he would be out of work fast in the airplane industry.
