From fresh to salt water - need advise

[majoma]

I am in the process of buying a 2000 Maxum 3100 with twin 5.0 Bravo II. The boat has always been in fresh water but I am planning to move it and keep it in salt water.
What changes should I make besides the zincs? Is there any way to flush the engine with fresh water after coming back to the marina?
I appreciate any advise.

As I am a fresh water boater I can only relay what I have learned from others as well as my limited experience with salt water. Make sure you have new "zinc" anodes on everything. Not magnesum (fresh water only) or aluminum (brackish water). If you will be in a marina make sure your galvanic isolator is working properly. Use a high quality hull paint. As your boat is probably raw water cooled I would recommend installing Volvo's Neutra-Salt system.

well...the first thing your gonna want to do is add a full up fresh water cooling system to each engine.....then modify the zinc's to the salt water kind....some companies offer a flush down kit in the form of tee's and hoses to be able to hook up a water hose and blow the system down...but the freshwater system is better......

That's exactly what I'm having done to my 3200. A San Juan complete cooling system for both of my 350's runs about $2400.00 plus another $1400 in labor.

Thanks for the suggestions.

Good bottom paint. If it's not pained now, make sure to use a barrier coat first, then botom paint. The paint you choose will have a recommendation for which barrier coat (theirs of course) to use and how to apply it. Follow instructions very carefully. Improper preperation will continue haunting you every year. make sure the drive and tabs are painted and consider painting the pickups too. If you store in saltwater, get used to checking raw water pickups and cleaning for growth frequently. check zincs frequently too and replace them eariler than later.

Best of Luck
