Raw water system



This is the main seawater strainer, which feeds the engine and the sea chest . The top of the strainer is above the waterline and can be cleaned out without shutting off the thru-hull.



Initially I was going feed the engine cooling water from the sea chest but after hearing of various issues (thanks Patrick) I chickened out and took a "T" off the main intake directly to the engine. A valve after the "T will allow me to isolate the sea chest in the event of a leak in any of its hoses, therefore permitting the engine to remain operational.

Is the Sea strainer located under the the Nav station seat????
Looks Good

Correct. I'm trying to create a boat where the parts that need regular inspection/maintenance can actually be reached without taking the place apart. How is the propeller test going?

is the strainer mounted to the bulkhead?

The Incredible Hull said...

Yes Sir. Firmly attached.

Is it possible to design engine cooling water without sea water? Use fresh water, because the mud and sand break the impeller and heat exchanger holes, thx

Charly. You could have an air cooled engine but it wouldn't be very efficient and a lot bulkier. I never found sand and mud to be an issue unless you ran your engine heavily while aground.
