What did you need to know? The main change was the strut depth. The old setup was about 1 inch deep to the table and the tube ran straight from the engine to the strut to set the angle. here is the current setup.

TRIMMING THE BOAT

The hull should balance about 18-19 inches from the transom without fuel.

The 7/8” inch strut depth is a good starting point. If the boat rides too light on the water, adjust the strut deeper. If the front sponson are running too hard on the water adjust the strut higher until the boat rides flat on the water but will not blow off.

The strut can be set up on the table at a depth of about 7/8” deep from the hull bottom to the table. Set the front of the strut about 1/16” higher.

Small adjustments to the strut angle can be made, also weight can be added to the nose or sponson tips to fine trim the hulls balance point if needed. Insert lead strips in the end of the pipe insulation, tyrap the flotation tube end to hold the weights at the tip of the front sponsons. More weight in the left sponson tip helps trim the boat balance point, add 2-4 oz. Once the boat is set up correctly no changes should be necessary for smooth or rough water other than adding weight to the nose. On a calm day the boat may spray water from the forward steps of the front sponson, raise the strut to lighten the boats ride, but be careful not to make it too loose when racing on rougher water. In rough water the boat may look like it is too loose on the water, do not change the trim unless the boat tends to blow off.
 
Thanks Phil

I have a copy of the instructions but they refer to some diagrams that I don't have just wondered if it was anything vital.

I'm replacing the strut, does it matter if it is bolted through the hull bottom or through the transom? The back of the strut ends up close to flush with the transom either way.

Thanks again
