I'm embarrassed to post this but here goes anyway. I didn't realize my old Voyager had transmissions. I thought the V-Drives were the transmissions and I've been diligent about checking the fluid levels in them and I've changed the fluid in them in the past. I'm not a boat mechanic but I can handle basic stuff like that along with oil changes, tune-ups, and winterization except for winterizing the closed loop cooling system. Since the boat has to be out of the water for that and I'm 2.5 hours away from the marina, I just have my marina take care of that at the end of the season when they pull it. This year though, the marina told me when they went to move it out of the slip to take it to the boatlift, the port side transmission wouldn't engage unless the RPMs were high. The marina said they added a quart of transmission fluid and then they were able to drive it to the lift. I'll probably be getting to the boat later this week and I'm just wondering if the transmission wasn't damaged from the lack of fluid. Toward the end of the summer when I was trolling, my speed would surge and then drop back down so I'm guessing it may have been slipping then. With a quick Google, it sounds as though the transmissions are located at the rear of each engine? I've been all over these engines changing spark plugs and water pumps and whatnot but I can't say that I've ever seen a dipstick other than for the engine oil. If I have a leak, apparently it's not a gusher but is there anywhere I should be looking? I'm just trying to get another couple of years out of this poor old thing before I upgrade. Is there anything I should be doing or should be concerned about? I'm just hoping someone out there has a similar rig and a similar situation. Thanks for any help!
