I just bought a 1989 Baja 250 sport. With a stock 330 hp chevy 454. Anyone know the top speed I should see with this engine?

I would guess at 60...plus or minus a hair.

First off you have a very classic cool boat, and it looks to be in very nice condition. As for performance, its not going to be a speed demon, I would guess with a 330hp your looking at 60mph. Just remember when it was built 60 was very fast, and still is very fun.

I would guess closer to 55.

That is my guess also..

I'll say 57-58 with a very good matched prop.

I'll say 55-56 with a box stock prop.

wiyh the right prop setup you will run about 53 to 55. I have the identical boat with 466 hp. the best i have ever seen is 62 gps. Great boats though!

Boat should run about 54 MPH GPS. Probably 58 on the "Dream O Meter". Don't get caught up on the speed thing, It will just screw you up. It will never end, you say you will be happly at 60 then 65 then 70 is great then you want 80.......

Be carfull the roller trailers are not good on the hull. You should get a new trailer or convert it to bunks.

Good luck, looks very clean for its age
