[dane112]

ok guys i recently bought 1993 regal valanti 230 sc... it had a 5.7 mercruiser in it.. i keep it at the mariner locked up and get them to drop it in the water when i use it... how often should this be flushed. i use the boat almost every weekend?

how often should this be flushed.

If used in salt water, for a good 10 to 15 minutes after every trip, for the longest life.
