    boat storage

    Dry slip seems nice as long as it allows for sour of the moment use . How long in advance do they need to get your boat in the water ?

    Risers - think I caught this just in time?

    I dont think that is from cooling water more likely condensation. The dry joint manifold prevents the leakage potential by separating the water and exhaust passages. also dont see any water streaks on them just rust and soot.

    3.0 engine temp never gets over 160 F

    Whose service manual are you using? Get a factory one if you haven't already. Pay attention to where your temp gauge sits now - as the impeller in the drive ages you will see the idle temp creep up, or at lest I did on my 3.0. Bottom line get used to knowing where they should be

    3.0 engine temp never gets over 160 F

    No marine engines run cooler than automotive applications. On a 140 thermostat 150 is normal. This helps with mineral deposits from the open cooling system and also at normal car temps in an open (non pressurized) cooling system it keeps cooling water from boiling
