    Trim Limit setting. 20deg?

    Hi, Just re-installed my MC1 sterndrive on the boat. The Trim-sensor was just a dummy (also no gauge in the boat). But there was a Trim-limit switch that was "bridged". So would like to put it back as it should. I read somewhere that a 20° - 25° angle is the max you should go while boating (to...

    Advice on Removal of manifold Mercruiser.

    Hi, Engine Mercruiser 165HP, 6 cyl in-line from 1970's. Engine is in the boat. To fix a crack I started removing the manifold. The nuts and bolts are removed and the manifold is "loose" from the block. But I still have the U-shaped elbow that keeps it connected to the exhaust. I removed the 4...

    JB Weld or alternative

    Hi, after some checks and feedback from this forum I saw that there has been done a repair (no clue how long ago) on the block, probably bad winterizing. I will remove the exhaust manifold to have a better look at it, but I expect it was repaired with JD Weld or similar (I see the grey repair...

    Size Jet's? Reference table

    Hi, Thanks to the input of the forum. My order for parts at Mike's is almost ready. :) I checked the 2 jets on my carb and I seem to read "49" (see picture). Or do I read this wrong? No info on the history of this carb. Does this make sense? I thought it should be closer to 60. But only based...

    5 Amp current in stand by. Normal?

    Slickcraft with GM inboard 6cyl in-line 165HP. No other accessories besides a inboard engine and the sterndrive. Yesterday I discovered that before even crancking my engine (doesn't run yet) it draws already 5A from the battery. This seems to be very high in my opinion. I will try to isolate...
