Don you posted the following comment and I would like to know if these specs, will apply to the 270,80,and 90 out-drives.<br />>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>><br /><br />" posted September 06, 2004 10:20 AM <br />--------------------------------------------------------------------------------<br />Here is what is in the Mercruiser installation manual. And trust me, that 10 to 16 degree transom angle is a must. If you don't have at LEAST 10 degrees, you are going to have problems with everything during the installation.<br /><br /> <br /><br />Here are links to drawing for a Volvo 5.7 and an 8.1. Both require the same size cutouts,stringers, and transom specs. as the Mercruisers.<br />5.7 DPS <br />8.1 DPS<br /><br />--------------------<br />Don S.<br />Ketchikan, Alaska<br />>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>>>><br /><br />I am re-powering from 305 Chevy/OMC to 350 Chevy/270 Volvo. Get the motor mount stringers level, then check the transom angle? If you or Rodbolt have any other ideas and comments on this swap, it would be appreciated.<br />I want to do it right the first time.
