    Mercruiser 6.2l 300 (2018 model) Gimbal bearing grease how to?

    Thanks guys for the info! Great to know Mercury tech support said nothing about any service manual beyond the one I have attached a photo of. $110.00 and 10 sections. Any ideas to what's occurring with the pronounced vibration in the lower unit when throttling up?

    Mercruiser 6.2l 300 (2018 model) Gimbal bearing grease how to?

    Hey Guys! Thanks for the feedback. Motor Serial # is: 2A578724 Bravo III I spoke to Mercury Marine and ordered a service manual, it didn't give me a darn bit of insight on how to grease gimbal bearing and spline. I believe the gimbal is sealed, the spline I believe it stated to grease every...

    Mercruiser 6.2l 300 (2018 model) Gimbal bearing grease how to?

    The manual states to grease every 50 hours I believe. I'm just not finding a zerk, however it is extremely difficult to get down in that area. Hoping someone has some insight, as I'm at 75hrs. or greater.

    Mercruiser 6.2l 300 (2018) fuel oil mixture prior to winterization?

    Hey All, Just checking if indeed running an oil fuel mixture from a small tank is something that is of importance prior to winterizing? I misplaced my manual briefly and believe it was stated to do so? Thanks!

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    @Scott06 @alldodge, The metal press plug is a 1/4", would I be safe with a 1/2" or 3/4" rubber plug? I don't want to obstruct water flow within the block. Thank you, Chris

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    On a different note, would anyone be able to provide some information on to properly conduct a pressure test on an open cooling system? Am I going to be utilizing the hoses on both sides of the T stat, or Sea Pump, or a combination? Also I've seen varying psi recommend, from 10-20psi. Any...

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    I'd say thats a good idea, and as simple or difficult to install a new rubber plug if it ever starts to leak in the future.

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    Something along the lines of this? Rubber plugs would be best over the metal? Or would tapping/pressing the original metal plug/s back in? https://www.amazon.com/pack-Rubber-Expansion-Plug-31mm/dp/B08B1V3BCQ?dchild=1 In regards to access, would you feel removing the exhaust mainfold would be...

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    On a different note, I removed the 2 bolts from the thermostat housing and attempted to remove. I could not get the cap to budge. Would you think the cap has to be twisted to get it to pop off? I tried hard to get it off, however no go.

    I just installed the new seawater pump impeller today, and the water distribution. With the exception of some dripping from the seawater pump hose (which was just a loose hose clamp), none of the hoses are leaking. Now that the new impeller has been installed it is pumping a good amount of...

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    Any idea of where to start as far as back flushing? I only will be able to get to certain hoses on the front of the engine. Should I pull the crossover cooling assembly hoses and run water through, hoping it pushes out the seawater pump hoses? The boat is a 2017, so fairly new. The T stat...

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    Update here. I pulled the drain plug from the seawater pump and felt a piece of plastic or rubber inside. I used a forceps like for fishing and stuck it into the drain plug hole, pulling out a few pieces of rubber from the seapump impeller. I just removed the pump assembly and yes the...

    Merc. MPI 300 Water Leak-Water Distribution Housing? & Winterization Question

    Hey Fellas, I re-connected the cooling hoses to the distribution housing and to the raw water crossover cooling assembly this morning.
