We used a 5 horse on our 1973 Catalina 22 .We would get about 5 and a half knots in three foot waves with it.We use a seven and a half horse on our 25 Oday thatis probably close to or over 5 thousand pounds. Your transom may not be able to take the weight.Don't forget you will be raising this thing evertime you sail or will be dragging it along.I really think that it is too much .
watch the weight as it concerns motor mount, transom flex and boat balance. New engines are all 4 strokes which carry added weight when compared to 2 strokes. Your boat would run very well with the Mercury 9.9HP. That engine weighs in dry at 84 lbs as opposed to the 15HP which weighs 112 lbs. Not to mention about $300 cheaper. Yes by all means try to get the 20" shaft.
I have been very happy with my heavy and expensive Honda 9.9 (?) "Power thrust" model. It has a large diameter 4 blade prop, and can be had in different shaft lengths. It starts every time, just sips fuel, and has charging coils to keep the battery up.
It's not an outboard but my volvo diesel is 22hp and the pearson 323 is #12500 dry weight. My brother had a 8 hp diesel on a 25' pacific seacraft. I rented a hunter 30 with a 12hp diesel. My Mac 26 did very well with a honda 7.5. 4 stroke outboard. It came with a 4 hp 2 stroke that did the job but I hated the noise and it didn't have reverse. We almost never ran the 7.5 at WOT because it went at hull speed at about 1/2 WOT. The worst thing about the Honda was Weight. It was a real bear to remove it from the transom in the parking lot..boat on trailer. The way the mac was made I could directly mount the motor on the transom. I would be very worried to have that much weight on a bracket. Not to mention the stresses involved in turning etc. If you go with a 15 hp be sure to have a very substanial mounting system.
