Overhauling R-985's for over 35 years

Picture
When engines need new life, a lot of customers send them to us rather than to the factory. Our full-service shop performs major overhauls on the common engines used in seaplanes: Pratt R-985 and Continental I0-520, TSI0-520 and 0-470. For top overhauls, any engine is acceptable.



Unlike many engine-overhaul shops, ours offers magnaflux, zyglo and ultrasonic testing. Since most engines we work on are intended for seaplanes, we routinely provide a little extra care. The R-985, for instance, gets an additional coat of paint up front and larger spark-plugs to keep out moisture.

For customers who need a fresh engine or cylinders in a hurry, we have 0-470’s and R-985’s in stock ready to go. Call for exchange prices.
If you’d prefer to do your own overhaul, we offer cleaning, magnaflux, zyglo and ultrasonic testing on your parts.
