The comment on high priced V-P parts
being available elsewhere is spot on. The MD-series (mine is the MD2030) uses Kubota parts
internally and was built by MTU the big European engine
building industry. Caterpillar, Northern Lights
you name it had the exact same engine
with just a different name. Under a different, new, thread I'll post the cross information for the MDseries owners.
Why a bigger engine? Why not? When it's needed the HP's are there. When not needed just throttle down. But there's more to it than that. The engine is just one part of a system. Fuel tank
, filters and lines - engine - transmission
- properly sized prop....it all has to work as a team. Mine starts with a dual 500C racors and finishes with a feathering prop that is 2 1/2" greater in diameter than the old fixed blade 12" prop. Bigger does not necessarily mean higher fuel
Finally run that engine at least once a month for 30 minutes or so at WOT (wide open throttle). It'll be the least expensive tune up you'll ever buy.
