Reviews and Testimonials

Adam helped us get out of a bind when our Vermeer BC1000XL Chipper went down right during our busy season. I called all over looking for an immediate drop in option but nobody had one ready to go at a reasonable price. We ordered the 4BT and it arrived within just a few days. Works great and we got back up and running with very little downtime.

We bought a 6BT Marine Engine from these guys for our SeaVee Boat. The entire process was hassle free from the first call with Adam until we installed the thing. Runs great, no problems whatsoever. These guys know their stuff.
