We make 40 year old R-985's better than brand new.

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 sparkplugs to keep out moisture.

Gordon Holbrook, our engine expert, has been rebuilding Kenmore engines for 25 years.

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.
