1E002730 300xs

Has anyone figured out a good way to
bleed the Uflex/Mercury steering. I need to bleed my system just not certain the best.
also what fluid is best?

Honestly not sure how to tell, probably merc as it’s the original from the factory. Don, do u stock the seals?

Need to replace end caps on Uflex steering, any advice/suggestions on what’s needed to make this job go smoothly.
I know new caps are UC128, however I notice most don’t come with...

300xs 1E002730

any issues with running these products at every fill up?

do they break down over time like fuel?

Greatly appreciated

I’m definitely interested in going with lithium at some point as well, curious to see why merc is against using lithium.

just wanted to confirm, the gap .44 is still a good gap for the 300xs engine. NGK IZFR7M plugs.
I plan to put a little die electric grease in the caps, would it hurt to add a...

Can u buy new or are the places that will do the lapping, that seems like a huge risk and I’m not sure i could get it 100%
pulling and reinstalling seems straight forward.

Is lapping the cages a “must do”

So little update, I read voltage at batteries as well as back at motor, seemed pretty close, no drastic drop. I did a “load” test on the batteries and everything checked ok, but load test back at...

So just follow the directions minus the drilling part? How can I ensure after rebuild they are functioning correctly?

Is there a way I could pin point it to a cables issue? A certain test, I hate to just go buy 20 plus feet of O awg wire as a gamble in hopes it solves the issue.

Thanks for the reply Don, I think it’s 4 awg, will double check, that being said, only one issue has this problem, other starts just fine.
i generally get both engines cranked and warm/operating...

How did u find the post on the pump rebuild, I’d like to rebuild mine but the drilling part made me think twice. After reading this I’m tempted again but want to read over everything. What are signs...

Hard to answer that as I don’t start them that much in the winter, I would definitely say temps are 40plus, maybe even upper 50’s.
engines will have sat a few weeks when I start them next time, so...

CCA is 1150, group 31 batteries.
distance from battery to engine is roughly 21ft
my load tester just puts a load on them with like a heating element and then shows good or bad.

Cold start after engines have sat say a few weeks, I have to merge several X2 batteries to get engines to start, or they just crank over using one. Merged, they pop right off....

excellent info, thank you. Do you send your rails, as well as injectors to Don to be cleaned/flowed?

Thank you, I did see where it was mentioned every 3-4 yrs on injectors, curious if that's still accurate as i have seen many say yearly.
I did not find anything that reference the white oil line...

:beers:

2007 300xs 1E002730 I put maybe 50 hrs a season on my motors, I do use non eth 91/93 fuel, as well as quickleen and quickcare.

How often do you clean/flow injectors? yearly seems over kill...

Curious, on these rebuild kits, it mentions drilling out the hole, is that really needed, I want to rebuild mine but hesitant because it talks about drilling out the hole, wish i had just bought the...

Had no idea that cap had to be lined up with the handle, thanks for sharing that pic. My levels seem to be all over the place and have been trying to figure out why. Possible bad float assembly in...

Replaced oil pump that was leaking, but oil lines going back on new pump did not feel snug even with a fuel line zip tie. Did oil pump prime and only ran on hose for a few min, got up to...

Don, most likely the case, engines are level and above the water for sure. The engine seems to run fine though, besides the annoying hot tub look at the dock. Can this be fixed without pulling the...
