    There is a mercruiser thermostat that is a direct replacement for the stock on that drops the temp down, they are about 15 or 20 dollars, search this forum for the correct part number,
    you can change it yourself there is a how to that used to be in the sticky section,

    Stock t-stats are designed to open at a specific temp range for many reasons that most do not understand (including fuel efficiency). Do yourself a favor and don't usurp that.

    I run modified stockers on all my performance skis-- all stock parts, just from different oems. If the oem design was good enough for a manufacture to offer a 5 year warranty with purchase and the design has not changed in the last 13 years, I feel pretty good about the design.
