Hi jarviswb<br />You start alot of new treads. It is hard to follow for us who wants to help. <br />Please read Suggestions for new posters <br /><br />From your profile I found out you have a 115 HP Mercury. That helps. You should post that information here. Now, I found this info on a swedish site. Is it a 6 cylinder inline? Then we have that right:<br /> 1150 (115,0) 3761035 - 4112634 1974 6 cyl inline <br /><br />
