Hi all, I know this has been discussed in the past but I am still a little unsure about something and fig'd I'd ask the experts. I blew up my 86 200 Johnny last summer (20 in shaft) I'd like to replace it with a 150 and have a great deal on a 25in shaft. I measured my transom and it is just over 20 inches high. What kind of problems/issues would I be looking at?<br /><br />Going on my 20' Pro-line center console (in pics)<br /><br />Thanks in advance everyone.
