Had an on going problem with over heating on my 150, XR2, for almost 3 years. Tried everything, still no resolution. Found out about US Boatworks on line. Drove down and within a 10 minute conversation with the guys was told two things that I had no idea was a problem. Bought a few parts, everything was in stock. These guys are "extreemly" knowledgeable to say the least. Told them if this fixes my issues I'd buy them all lunch. Guess I have to go back, I owe them lunch. tom elderTrustindex verifies that the original source of the review is Google. Parts and service department the best in the city. I don’t go anywhere else
Most Asked Questions
What's the difference between a remanufactured, aftermarket, and new OEM lower unit?
Remanufactured is your exact unit rebuilt to OEM specs using genuine OEM parts — near-new performance at a fraction of new OEM cost.
Aftermarket is built new by a third-party to OEM specs with aftermarket parts at a lower price point.
New OEM is factory-built by your engine’s manufacturer — the best available.
Not sure which is right for you? Call us and we’ll tell you straight.
Will this lower unit fit my engine?
It will fit if correct specs are given to us. Provide us your engine model number or serial number and we’ll confirm compatibility before you order. Forty years of experience — we don’t guess.
How fast will my order ship?
We try our best to ship your unit out in 24 hours, most times we ship them out the same day it was ordered. Some units may need to be built in house. If this is the case, we call you with an estimated shipping date. We prioritize getting these units out as quickly as possible. We will also send you a tracking number the moment it leaves our warehouse.

Often yes — and most boaters don’t think to ask. Call us for help. Our owner handles every claim personally and works directly with your adjuster.

Many of our customers are do-it-yourselfers and if your comfortable with install, by all means, do so. If you prefer not to install yourself, we can ship your unit directly to your boat shop so they can complete the install. We ship thousands of sterndrives directly to boat shops each year.
