Oil keeps leaking from this plug on my 470 trim pump. The plug is difficult to remove and I have changed the oring twice but it keeps blowing a chunk out of the oring and begins to leak heavily. Any ideas why this keeps leaking. Thanks.
Are there any videos of mc1 bellows replacement? Also are there any tips and tricks to replace the bellows. Ive never been this deep and would like to know how to replace them before I begin .Thanks
doea this shaft run in gear oil on the top. I noticed there is an oring on the shaft and there is a seal in the upper half that also runs on the shaft. Thanks.
I removed my mc1 drive to pin point a gear oil leak and when I pulled the drive there was water in the upper bellows and the u joints were rusty on the drive input shaft. What do I need to fix. Thanks
I have a 1977 470 mc1 and the drive oil is leaking from a passage above the seal carrier for the prop seals. There is a passage (maybe the exhaust exits from) which gear oil is running down from and making he carrier appear that it’s leaking. I would like to know where the oil is coming from...
I pulled the seal retainer to install prop seals and now gear oil runs out of the prop. Do I need to add sealant where the retainer touches the gear housing? Thanks. 1977 470
I tried to remove the lower prop seals in my mc1 drive and am having no luck removing them. The problem is there is just no room to work with. I tried to drill a hole in the seal to allow me to use a screw to remove them but there is not enough room to drill. So I proceded to plan B, trying to...
I am wondering if anyone has ever used a carb spacer for their rochester carb on their mercruiser. I am wondering if it would increase performance make it start easier and if it would prevent vapor locking? Thanks
Where does a 470 usually vapor lock at? I have already installed an elecrtic fuel pump between the tank and the factory fuel pump/water seperator. Do they tend to vapor lock in the metal line from the factory pump to the carb or.do.they vaporock in the carb itself? Thanks
I am installing a new lower shift cable in my mc1 outdrive. I removed the old cable and am going to install a new one. Two questions, first off where do these two plastic pieces go and do i need to replace them? Secondly i am looking through mercruiser manual #2 and thet list several drives...
I have been toying around with the idea of adding a fresh air fan to feed my carb on my 470. Should make it run stronger and hopefully help with warm weather vapor locking. Any opinions on this. Thanks
I need to install a new lower shift cable in my 1977 mercruiser 470. Just wondering if there were any videos out there of this process. Its always easier to watch a how to video before i tackle this thanks.
I need to change my lower shift cable in my 1977 470 mercruiser and I was considering changing my bellows at the same time as im not sure when they were changed last. Is this something I should do or will I get myself into trouble fixing something that isnt broke? Anything else I should replace...
I have a 1977 mercruiser and I am wondering how to adjust the adjuster underneath this plug and what is it's purpose? It seems to affect the trim motor. The farther I turn the adjuster in the harder the trim motor has to work to lower the drive. I have already messed with the settings so I...
Is a 2 solenoid trim pump the same as a 1 solenoid. I need to replace my valve assy as the motor part works fine and i found one close, but it is a 2 solenoid set up. Can I remove 1 solenoid and wire it like my original to make it work? Can I remove the screws on the bottom and switch the...
