repowering my V20. need some advice

[Airslot]

You guys have overlooked one big thing so far. On a 25" transom you would hang 20" motors if going twins. If you want those 25" motors you would have to rebuild the transom to 30".

good point air, personally if i had the money, I'd put a 175 Suzuki 4 stroke on the back of it and take a litle extra money and buy Sea tow to get back in if soemthing goes to crap

I have never heard of 26" shafts either however, if they DO exist, you could probably mount them in the top holes and be okay (for a single engine). I built my transom to 25" them mounted my engine in the second mounting hole which probabaly raised the engine 1-2 inches. Also I have seen and old Maco and an old Grady with 2 right hand engines. However I agree that a single 150 or 175 would be your best option.

i have 740 pounds hanging off the back of my boat and the boat can handle it but, and i mean but, do not do it if you dont have trim tabs. then it will ride horribly. i wish i had twins on mine. in a perfect world and you were going with twins. dual e-tec 90's would be freaking sweet.

Well i called the guy at the dealer today and this time he let me talk to a tech. sure enough, there 25" shafts lke i thought. he also told me that you cant make one reversed rotation so my option to run duals wont work. the good news is, that if i just wanted 1, it would bolt right up. im just not sure if i want only 115hp. i have found some 175s and 200s pretty cheap but there all used. i would really like to run a brand new motor with this boat since i plan on putting alot of hours on it once its done. what would be the best deal on a brand new 175. or better yet twin 90s like cterrebonne was talking about?

on those 115's you were looking at, you dont necesarilly need to run a counter and the std lower unit if you have a seastar hyd steering. i know for sure BRP doesnt make a counter in a 90 hp. we installed twin 90 etecs on a caroline dlx 24 and it ran very well and the steering torque wasnt noticeable. but like youre saying they are 25" legs and you would have to make you a 30" transom. im thinking if you didnt mind the headache of building the transom up i would run the twin 115's and keep a spare prop in the boat in a large blade 15" pitch. that way if you blow one up you can swap the prop and get back in on plane with out stressing the engine. it looks like a win win with twins. more transom height. more power, and more safety. plus twins are cool.

The original twin 70s on my uncles' V20 were both standard rotation. Not sure if the 140s on it now are counter or not. I don't think I've seen any pictures of V20s with twins on this forum.

interesting. whats the reason ill have to build my transom up to a 30" to run 25"s? the main reason i would rather run twins is to have a back up if something goes wrong in the gulf. with my luck, it will.
