Spring is finally here with high temps in the 70’s all week.  It’s great to be out enjoying the sunshine and what better way to do it than getting your boat out? Before you take your family and friends out on the water for the first time this year, it’s a good idea to make sure your  sterndrive engine or outboard motor is top running shape. Below is a list of some things to check before taking your boat out. This list does not represent everything you should check but does give good suggestions of where you should start. Please consult a certified marine repair mechanic prior to working on your boat motor.  It’s also a good idea to consult your owner’s manual for boat motor maintenance guidelines and instructions specific to your boat model.


Belts, Cables & Hoses
-Always check for cracking that occurred during winter storage.
-Control cables with cracks or swelling on the outer layer may indicate need to replace.Belts should fit tightly around the pulleys to prevent slipping. A worn belt may have a black substance near the pulley & also may fit loosely.
