RE: First gasser, Prestwich Sigma51
When you glassed the tube in did you put the next size tube over the prop tube first? reason i ask is it makes things easier if you ever need to remove it, at the transom just silicone it in but def make the hole a slot for adjusting things.You dont need trim tabs you can trim the boat with the drive angle and rudder by raking the rudder back or tucking it under which alters the hull attitude the same as tabs do.How do you plan to balance the hull usually most people leave mounting the motor last so they can move it arround to find the balance point?.
