‘74 20’ SF new transom

[DonV]

Very nice results....now the fun part. To answer your question I only have experience on the 23'er with a manual jack plate. If you are at 27" on your transom I'd try the engine without the jack plate, then if you wanted you could put on the jack plate later. I think at 27" you should be able to get the engine mounted perfectly, my 25" was just too low, by about 2" of course, and I went with the 6" plate.
