    What’s this small tube do? Pics incl.

    A water Pressure Gauge will measure speed over the Water, which is better for Skiing on a River, than a GPS which which only measures the speed over the River Lake Bottom, and can't take current into account.

    The Pressure Speedo is measuring the Speed across the Water, doesn't matter if the Water is moving. GPS will measure the Speed across the Lake/River Bottom. I can see many people bragging how fast their Boats are, using a Distorted GPS Reading, cause of a Current.

    Point setting vs timing

    99.9% of the Time, setting New Points @0.020" will get you the Correct Timing. Using a Flat Feeler Gauge on used Points, all bets are off, and the Timing Marks and a Continuity Meter/Light are a better choice

    Don't put too much Faith in GPS, as it is measuring Ground Speed, and doesn't take a Current into consideration. Boating on a River, in one direction the GPS may read 45mph, and in the other 25mph, when the Current is 10mph.

    Welcome to iboats That Hose sticking out of the Motor is the Pitot Tube Hose for Speedometer Water Pressure. The Hose zip tied to Trim Wiring Harness, likely the Hose going to the Speedometer Gauge

    Conversion from I/O to outboard on Islander.

    Few Fiberglass Boats use Knee Braces, They rely on the Glass around the Transom combined with the Motor Well on Outboard Models and Hull Cap on Inboard Models, combined with the Engine being bolted to the Stringers and to the Transom, which may or may not be full Width, to be the Transom's...

    How much Prop should i try?

    a 4th blade will certainly load the engine more, and kill top speed by several mph below what a 3 blade would do. Having the WOT range of both engines will certainly be of help, in making guestimates

    How much Prop should i try?

    First of all, what are the WOT Rpm Ranges for both the Old and the New Engines? What WOT rpm were you getting with the Old Engine? If the new Engine has a WOT Range that is higher than the old engine, you might not need a pitch change. Now switching from One Prop Line to Another, often isn't as...

    Transom replacement or design flaw?

    A Strip of Right Angle Aluminium along the Board bolted thru the Transom will certainly stiffen it, another along the Top of the Transom, would also raise the motor a 1/4" or so too

    cracks around bolt holes transom

    Being that there are cracks several inches away for the Bolt, I too will assume that that Core has deteriorated. Or was crushed by an Overzealous Rigger with an Impact Gun, and the Glass has succumbed over time

    Can not stop wanting a Butterball Turkey.

    The USDA considers 165 the Minimum for Ground Beef, less than that is Unsafe. Myself, I go for minimum of 185, often higher.

    With luck, all that salt in the Brine will reduce the number of Bacteria. Happy Cooking!

    Cooking it to a Lower Temp, Longer, creates the Best Environment for Bacteria to Multiply like Gangbusters
