What to know before you buy
Compatibility
Marine fitment depends on engine family, gas vs. diesel, drive type (inboard, sterndrive, outboard), gear ratio, and rotation. Raw-water vs. closed cooling and exhaust configuration matter too. Give us the model or serial and a specialist confirms the correct configuration before it ships.
Used vs. Rebuilt / Reman
Low-hour used marine engines and drives are ideal when a clean core surfaces. Rebuilt/reman units cost more but reset wear and warranty — often the right call for repowers and hard-to-find blocks. We'll compare both against your season and budget.
Warranty
Coverage differs across used, rebuilt and reman marine units and by supplier. Exact terms are set out in your written quote before you buy — no surprises at the dock.
Freight & Delivery
Marine engines and drives ship LTL freight, typically 2–7 business days. Crating, liftgate, and marina/residential delivery are quoted per destination.
Frequently asked questions
What determines the right marine transmission?
