Funny story about the impeller puller… I bought one from Moyer last fall and admired it on my desk all winter. “Oh what a pleasure it will be to use this clever tool” thought I, over and over.
This spring I went to use it and found the two prongs weren’t even close to a fit into the spaces inside the pump. Gloom, frustration… wrote a ‘how do I use this thing’ message to Moyer.
Then….
I looked at a youtube video on Moyer’s site showing use of the device. The two big red plastic knobs come off. They’re just there to protect the ends.
Off they came and presto, the puller worked effortlessly. I had a laugh with Moyer about it afterward.

> I used to have an atomic 4 on Candy Cane before repowering to electric, and what I remember of the water pump location isn't somewhere that access would be meaningfully improved to by a new hole in the cockpit. The water pump is basically diagonally down and forward of the forward bottom edge of the cockpit well, so a hole in the sole would be too far aft and oriented the wrong way, while a hole in the forward side of the well would be too high. The recommendation for a hole in the plywood panel making up the inboard side of the (starboard) cockpit locker seems the most reasonable to me (assuming the fuel tank isn't in there). Alternately, there are some people on the list who have replaced the original deck plate in the cockpit sole with a considerably larger hatch, which might allow enough of you to get far enough in (upside-down, of course) to meaningfully improve access to the pump.

> Really though, the best thing I can think of for improving the ease of impeller removal is to make sure that the screws holding the plate onto the back of the pump are hex-head screws that you can use a socket and ratchet to remove/reinstall, rather than having to reach farther over the engine to keep a screwdriver properly seated.
