What size shaft for a v20 bracket

[spareparts]

most conversions( not V 20's) Ive worked on use a 25 inch shaft engine, but seem to have an issue getting the engine high enough once installed. Personally, Id use a 20 inch motor, mount it so its 5 inches higher than it would be if it were transom mounted, and raise it up from there depending on how it performs.
