I have been procrastinating for too long now on getting the VSPu's set into the hull, and so decided to do so today, starting with the stern unit........also it will give me a better idea of what I have to do motor wise for the unit.
started by marking out the circle to be cut from the grp mould, and drilled the perimeter of the hole with a 2mm bit...........and then using the side of the drill bit as a router I joined the holes and made a bigger hole.
Once this was done I fit the locating ring for the unit, and it fit where it touched.........so out came the dentists reamers and I cut the grp back for the ring to fit in properly.
They will be set in with polyester filler tomorrow.
