Thanks, I ordered the repair kit $90+, it includes 2 ball bearings and shaft seals, impeller, cover plate screws, gaskets and o ring. No shaft or axil as Volvo refers to it.
Best price on a new pump $325. Most suppliers refer to the Johnson pump F7B9 # 10-24277-3 as obsolete or no longer stocked. I will make a decision on buying a new pump after I rebuild the original.
My pump research did discover the engine driven pump specs are 26 GPM @ 1750 rpm and it has a 10 ft head and most be mounted below the waterline so maybe an electric pump is still a possibility.
Also for TMD31A Manatee owners if the turbo goes bad it can be deleted using a filler tube and the cylinders are sleeved so the engine can be rebuilt.
