Some boat engine parts offer a challenge to the weekend DIYer but with some research, patience, and perhaps a mechanic on speed dial, these maritime engine parts and chores might be right up your alley!

Thru hulls and other professional jobs

Installing sea strainers, circulation pumps, and ball valves all require a thru hull at some point in the project. Drawing the line at putting a hole in the bottom of your boat may be a wise choice but plenty of boat motor parts are available to order for your mechanic! Defender also carries an extensive line of replacement motor mounts (also a great job for a pro!).
