Default Hull construction

Hey everyone new here..
I have a 92 sr1900 3.0 bowrider
It was owned by an older couple so its in great shape but i have a few questions about the hull construction..
Is there anything i need to watch for with this boat.
Is the 3.0 stringers constructed the same as the 4.3 making it possible for repowering. I know the 3.0 is center front mount. But are they built the same between both power plants..
In the shape its in i plan on owning it for awhile so any help or info would be great thanks...

Welcome aboard

Very clean looking boat. I cannot answer you stringer question however if you plan to drop in a 4.3 you will also need the drive to match as the 3.0 drive has a different gear ratio which will not allow the 4.3 to operate at the correct rpm.

Thanks..
The 3.0 moves along pretty good under proped 59kph gps but over reving to get there ...(not good)have a 17pitch on it right now..
Repowering will happen when the 3.0 wears out..
Any ideas on prop pitch? I know it will be ok with a 19 but im not sure if 21 will be ok or not

You may what to try quicksilver' prop calculator to see what it recommends.

If it doesn't need a new motor, then i would not repower at this point. Don't worry about the stringers on the boat. Worry about the engine mount locations on the engines themselves.
