Hmmm…So the grommets in the upper exhaust are at different levels then…Will have to look at the parts breakdown…Glad it is working fine now though, don’t argue with success!
Look at the first pic – you can see the lower grommet where the long return tube fits. They must have made a mid-year change in the design as there are two different impeller housing caps. One is plugged on the side of the upper return and one is not. The parts diagram is misleading. It is actually correct for the 30D motors with the short return tube.
Still confused, those two grommets on top of the water tube look to be at the same height to me…. I know that the lower pick up pipe (from water pick up to impeller cap) was a change for that year….Oh well, this is something I guess I would have to see in person to understand…I did look at the parts breakdown again and see the two different end cap part numbers, but don’t understand why/how they are different…. I saw the two different part numbers for the upper water tubes, just figured where they plugged into the inner exhaust housing was different…How much longer is on tube than the other?
About 5″ longer. I thought the previous owner had tried to use a long shaft tube since the motor was born a long shaft. Someone had converted it to short shaft at some point. I guess a long shaft return tube would be an additional 5″ longer.
