Question New here and to boating

Hello everyone, been wanting to get a boat for years and I just pick up a Maxum 1800 runabout with trailer for $200.00. Anyone have any information I could get? Specifications, wiring diagram ( I know I will be re-wiring it), engine/drive information (stern drive)? Anything would help. I it going to be my winter project and I want to do it right for next season. Thanks....

Tex welcome aboard.

I recommend you getting an aftermarket mercruiser manual it will have the engine and helm wiring diagrams. I won't have diagrams for nav lights, blower, ... but these are pretty straight forward. The manual will also tell you how to service he engine and drive.

Does the engine run or at least turn over? What engine is in the boat? Be sure to replace the water pump impeller in the outdrive (see manual). Also inspect exhaust system as it is water cooled and clogs or rusts out over time. When engine is running use a handheld IR temp gun to check temps around the engine all should be no more than 160 F

Good luck and let us know if you have additional questions.

Welcome Aboard OhTex!!!

There is not enough information to accurately address your question:

Make: Maxum
Model: 1800 (1800 SR; 188XR, etc?)
Engine: Mercruiser
Engine Model/Size:
Outdrive: Alpha 1?

Wiring Diagram: Owners Manual
Outdrive maintenance: Outdrive Service Manual
Engine maintenance: Engine Service Manual

$200 seems very, very inexpensive. I would start by verifying that the floor, stringers and transom are in good shape and there is no rot. If the floor has rot, then the stringers will as well. I would not spend a dime on anything until these are checked out. I would not spend a dime fixing anything if there is rotten stringers or transom.

I don't want to sound negative, but this sounds a lot like 'free boat disease'.
