Merc 2.5L on Seafari?

[fdheld34]

If I were to raise transom to 25" and had 20" shaft..I would want to purchase 5" extension as well...keep motor as high up out of water as possible especially when in the ocean. Also, purchasing a 20" shaft motor from bass boat will usually be corrosion free (especially tiller arm bracket etc from me shopping around last year) and then add 5" extension when time comes to enclose/raise transom. Seems to me that you would be defeating the purpose of raising transom to 25" and then use a jack plate to lower engine. Or you could buy a clean 25" shaft motor and use a 2 piece fixed height jackplate on your 20" transom until you enclose/raise transom (watch that waterline though...did it on a 18' formula with a 150). I think I am getting off topic..my apologies!!
