    Question 1988 19' 4.3L OMC Cobra Donzi Ragazza - Info?

    Greetings Everyone,

    I am brand new to Donzi.net. I recently purchased my first boat which is a 1988 19' Donzi Ragazza Bowrider with a 4.3L 2 Barrel OMC Cobra stern drive. Does anyone know how I can get info or specs for this boat. According to Donzi they don't have anything due to the OMC bankruptcy - I guess records were removed for legal reasons.

    Some things that would be nice to know:
    1. Horsepower
    2. Recommended RPM range
    3. Fuel capacity

    Thanks a bunch.

    If memory servers me correctly, the 4.3l v6 on the OMC engine was 190hp.

    Not sure on the fuel capacity, my 21 held around 50 gals.

    Good luck to 'ya!

    Yours is not the stated 128HP, that was the 4 banger. You could walk faster then it ran!!! Bubbles (Mr. Sub man) has it right 190 w/ a 2 barrel and 205 w/ a 4 barrel. Enjoy!!!!

    Yep I have the same boat accept with a merc 4.3 and it came with the 2bbl carb. it has a 30 gallon fuel tank top rpm is 4800 but i run mine up to 5000 every now and then without issue 2bbl is rated for 175hp 4bbl is 205hp. i put an edelbrock 4bbl carb and intake on mine with a plastic spacer between intake and carb. with that upgrade I had to go up 2" on my prop to a 21" lab finished stainless. It runs close to 50mph with that setup and just me in it. I also have a steel cobra hydrofoil on my outdrive it made a big difference in getting it out of the hole and it lifts the stern allowing me to use more trim and it rides much smoother with it on there. I love it I get compliments on it everywere I go. It rides and runs great handles rough water better than bigger boats and much better than any other bowrider of the same size. it could handle a bunch more power and speed in my opinion just havent had the money in the last several years to stuff a nice small block in it. and with gas prices the way they are maybe thats a good thing right now. ask away on the questions i wont be on here everyday now so be patient, now that we have switched over from Cingular firewall at work to at&t firewall this site and just about every other good one is blocked from work.

    Thumbs up Thanks Everyone!

    I really appreciate the rapid response and information from everyone. This looks like a great network.

    To: MikeV - I've only taken it out twice but have received compliments as well. The boat is in overall good condition but had sat a while before I got it. I've replaced the starter, fuel pump, fuel filters and tachometer, done a lot of cleaning (both on the interior and electrical connections), inspected the lower unit, etc. It runs like a top and is a very comfortable boat. A matching Donzi trailer came with it. I gave $3,000 for it, which I feel was a pretty good deal - what do you think?

    I haven't been called bubles in a while ,......

    by the way, did you ever blow bubbles?

    Anyway, my 21 ran pretty good with the 4.3 (4bbl version), and ran even better with the 350,...

    but in my opinion, enjoy the Ragazza for what it is, don't do what I did and spend 7k making a 60mph bow rider.

    I didn't listen, and you may not, but I WISH I had put that 7k into my X-18 and had never touched the Ragazza for speed, but had left it stock.

    I agree with Wayne you will never get your money back out of it so if your going to do a motor swap really think about it. We have 3 kids use it all the time and I can fish out of it quite well so I will be hanging on to it for a quiet a while and i will probably wait till the 4.3 blows to do it then it will be a more justfiable in my mind. 350 crate motor is only about 500-600 more than a 4.3 then a bigger prop and new exahust will bump it be at the most 1500.

    I agree with MikeV,especially with Gas prices and the time of year. Mike does use his boat a lot, but is always tooooo busy to drive over to meet me up here on Taylor creek. I guess since I am not a Regazza guy he is being a snob.

    Yes you can get up here no problem except all the ramps on the lake are closed except for 4. I took the Corsican out today at Tidwell almost everything on my side is closed.

    We have put in at Charleston since it still has a dock in the water and is closest to where we are. I didn't get the boat ready till the middle of July so only been out twice. I was thinking about going for a run Friday after work if I get the OK from the wifey. are you all keeping the boat in the dock or on the trailer maybe we can meet up run then get some dinner if it doesnt rain.
