I am looking at a 91 sx 150 and I have some questions 1. nada blue book does not list a sx150 in 1991 last year was 1990 is this correct? 2. are there any problem spots to look at on this boat? 3. Where is there wood in the boat (transom/stingers/ decks)? 4. Has a suzuki 115 on it how is this motor and what is max on the sx150? Motor is running rough boat has new trailer what is a good price on it? Thanks Randy

Not sure about the year on the boat. That could just as easily be an error by NADA.

As for the boat.  Almost all boats back then were constructed with wood structural support in the transom, stringers and usually deck.  On that Skeeter you REALLY need to look very closely at the transom for rot.  That vintage Skeeter was troublesome for rotted out transoms.

As for the motor.  I've always been told that Suzuki's were great motors when they ran right.  If they didn't run right............

No idea of the max hp on that model either.  115 is probably it or it might be 90.
