I just bought a 76 waikiki 21ft daycruiser minus engine.All sterndrive parts are there (Its a volvo penta) except however it bolts to the flywheel.Its a volvo penta.Newbie so not sure of names.lol.I guess i need a pto? Is this right where can i find one does anyone have a pic????Also the boat had a 351 in it prior,thinking or a 396 or even a 460 going in to it.Do i just get a pto to fit the flywheel/engine of my choice?.Thanks for any input....Daniel
