I have a Tullio Abbate elite 30 with two vortec 7.4 engines ,bravo one with mirage 23 P props and I can not go faster than 50 mph. I did compression test and it came up perfect , I put new plugs , plug wires and distributor caps , etc...

Do you think is the max I will get out of those engines or there has to be something wrong .... my point of view is that it should reach 60 easy... with my previous boat a 24ft and a single engine 5.7 I got close to 50mph

thanks for the help!

You need a baseline 1st.

That baseline is what your exact model boat did with stock 330hp motors. If it is much better than yours, then find what props it used.

Last thing anyone wants to do is assume there is an issue and chase a non existent ghost all the way until you sell it.

Thanks... the main issue is that being an old boat I bought it not on the better shape possible with some small issues , the last owner said it hit 65 but you know about those figures, almost all lie ... the other issue is that this brand shot down and to get in touch with them is almost impossible ... so basically I am looking to do is create a check list of what to do... and what to check first before I start spending lots of money...
