Just bought a 1976 16' o/b, putting on a 2.5L 200h.p., 20" shaft. Anybody else have an outboard? What h.p. are you running ? How about a jack plate ? How does boat run w/ o.b. compared to what I heard about sterndrives ? HIGH LIFE

Never been in one but that should be one helluva ride.

Remember they were rated for 135hp max. Somebody on the board has one with big power. I also think there was a guy on the board that went over 90 on one with a hopped up engine, his name escapes me at the moment, being over 60 years old has its issues.

The only plate my boat has is the aluminum decal at the back seat. It just shows H.I.N.,motor and drive are blank. No C.G. plate for passangers or weights!!! I will add a s/s plate to renforce the transom. Trim tabs are Bennett. Can anyone guess what I should use for a prop ? HIGH LIFE

Hello,

I am a new owner of a 1972 Donzi Sweet 16 Classic with a Johnson 150 HP Outboard. I live in So. FL, and I have not taken delivery yet, with the boat coming from NJ. I have 18.5 years power-boating experience (mostly high-performance PWC and one 120 HP Stingray bowrider). I am new to Donzi ownership.

I appreciate any advice about owning this Donzi model. Pointers based on real experience and lessons learned from a real owner would be best, if possible.

First initial questions are these. I am nowhere ready yet to implement these items, but am curious as hell.

Q1: How much outboard HP (and weight) can be installed onto the Sweet 16 hull?

Q2: If necessary, can the transom be reinforced for more strength to handle more power?

Q3: What are the physical limits of this boat, say when running WOT in flat water: hull strength, handling, porpoising, keeping the boat in the water, etc?

Q4: Thus, what top-speed is attainable with maximum power and how do I get there from here?

Q5: What other advice about the Sweet 16 can people share? What hard-earned lessons have you learned?

Thanks in advance for any seasoned advice. Regards,
