I have a used 28x10.5 ft fiberform that I am re-powering. It has twin 350's now that are old, tired and have sat for about 2 years. I am going to buy rebuilt 350's and upgrade to 300hp. My question is if I need to have them in reverse rotation. I thought you for sure needed it and the way it used to be done was at the motor. I thought the way it is now, the rotation is changed in the outdrive so you just have standard rotation motors. I talked to a few manufactures, mechanics and knowledgeable others and they all said different things (of course). I have alpha one outdrives. The props that are on them look to be the same rotation, so I assume they were spinning the same way. I can not tell if the motors are reverse because I can not read the firing order or serial numbers. It does not really matter what is on there now anyway. I am more interested in what should be on there later.
So what is the deal? Does a boat that big need to have reverse rotatation?
If so, how is it done. At the motor or in the out drive?
Sorry if this has been hashed over before. Like everybody says, the search function is a mess.
