"Get the larger boat(19')
Do not under power it.
Minimum 150 H.P.
No 115H.P. or 135 H.P. motors will do.
If you decide to go with a larger boat(20')
Nothing less than 200H.P.
The boat will perform to it's high end range and if you decide to sell it it will be easier to sell.
Check the transom, floor, and stringers
Have a certified mechanic check the motor. Best money you will spend.
Put the boat in the water and fish it. Don't just drop it for a few minutes and put it back on the trailer.
Power up all electrical components.
Go over the trailer from end to end.
Make sure the titles are current and available.
If the transom is weak, stay away from it. It's a minimum of $4,000.00 to repair.
Compression should be within 10% on all cylinders."
This is sound advice.
