Boat motors

I am looking at buying my first boat. We want a 30' cruiser or a house boat. Some of the ebay and craigslist boat say that they are "fresh water" boats. Since we expect to use the boat in brackish and salt water, is there a difference between a salt Can a Fresh water boat be used in salt water?

Short answer yes they can BUT they would need to be washed and rinsed after every use in salt water plus the engine would need to be flushed witrh clear (fresh) water after every use also. That means hooking to a flush hose or muff as they are sometimes called and the engine ran for some time to flush out the saltwater. Saltwater engines are coated with corrosion protection both internally and externally and with extra sacrifical parts to draw the corrosion to them. These parts need changed when eaten too badly to help protect the rest of the engine. It would be more convenient to have a salt water boat. The cost is not that much more for the convienence of not doing the flushing out and washing.

Typically, a description on E-bay/Craigs list is intended to convey the idea of where the boat has been used during the majority of it's life. That's because a salt environment is quite a bit harsher than a fresh water environment - and can take years off the projected life of a boat. Hence everyone's propensity to tell you their boat has been "fresh water only".... It's a selling point.

That being said - all boats are both "fresh water/salt water". The biggest difference between salt tolerance is the quality of the boat, materials used, and size of your wallet (not to mention regular maintenance/cleaning).

Is your prospective boat steel/fiberglass/aluminum/etc. Does it have SS fittings, or aluminum/brass? Is it inboard or outboard? If inboard - is the cooling system open (raw water for cooling) or closed (with a radiator type system using fresh/treated water in a closed loop). Do you plan to trailer it - or keep it moored in the water year round?

Once you've decided on the type/brand of boat you want - and the propulsion system installed - then it's time to look at the materials/quality of the brands/motors that you've chosen --- and weigh the pros and cons of each to come up with your final decision.... then it's a simple matter of finding that particular model at a price you want to pay....

Keep in mind that all the above is just the starting point - regardless of what you purchase - you will need regular and consistent washdowns - engine flushings - diode inspections - bottom paints - etc., just to keep your new toy looking/running good.

Good Luck - and have fun...

Like said a boat is a boat put it where you want .Fresh or salt water . Its a hole in the water that you put $$$$$ into.
But in the salt water you do want to keep an eye on the Anodes on and in the boat. From rudder,hull ,shaft and engines plugs. You said 30ft . Might also look into one you can hang overboard Called Grouper anode. This is used to combat stray current from defective shore power. When you tie up and not on the hook.
