Trying to figure transom angle
 

so i'm trying to sell an old bracket i have laying around and the guy needs to know the transom angle. i have no idea how to figure it out. any ideas?
pictures would be great as someone tried to explain it to me and it was like he was speaking chinese.

Not sure if this is what you're looking for. But it's a start at least. He wants to know the transom angle in relation to what... the keel? Go to Harbor Freight and buy a machinists combination square http://www.harborfreight.com/12-inch...set-92471.html Put the rule flush on the keel and the compass flush on the transom. Read the degrees of angle on the compass face. :head:

thanks guys. problem is the boat no longer exists. i only have the bracket.

Then reverse the equation. Hold the long straight edge along the top of the bracket and measure the distance from the top angle to the inside of the square. It'll give you the same number then as the site says, each 1/4" equals one degree of transom angle.

I know very little about gill brackets, so I admit that I may be mistaken here, but to my way of thinking, since the engine pivots on the rear of the bracket, the whole thing should be academic since you can just adjust the angle by trimming the engine.....no? :head:

Well, yes to a point. Then you have to worry about placing shims to correct for (usually) lack of ability to kick the engine under the boat enough to prevent porpoising.

Got one boat that needed shims. With the engine all the way down, it still wasn't enough angle on the transom to prevent porpoising.

Did you do that on porpose?












(sorry)... no really, sorry :you:

It does...but before you get to that point, you want the bracket to come STRAIGHT off the transom of the boat....so the angle of the transom and the angle of the front mounting surface have to be the same...
