I have a friend who has run outboard jets for many years (including many years as a lodge owner). He swears that adding a few thick washers to the top mounting bolts really helps a jet hop up on plane by adding extra downward thrust (increasing the tilt) and thus lifting the stern.
This is my second jet skiff. My first boat (1652 MVJT) I added flotation pods to and that helped reduce the bow rise when running alone. The boat also floated much more level at drift. My new boat (1860 MVJT) doesn't quite suffer the same amount of bow rise. But I am thinking what the heck I may as well try this thick washer trick. I am also interested in trying a 4 blade Stainless steel 7 3/8 impeller on my Honda 90. I am currently running a 7 3/16 4 blade Stainless steel impeller.
So has anybody ever tried using either transom wedges or used washers to increase the downward thrust on their jet skiff?
