    Increasing MC-1 trim range

    Hi I would like to increase the amount of 'in' trim range on my MC1, ie get the leg to tuck in more to get increased nose down force. Currently, at full down trim the leg is still in an almost vertical position. The trim rams appear to be going to their normal position, ie stopping at the paint...

    Swapping GM petrol engine for a diesel

    Just considering future options here, but if I were to swap my Mercruiser 228 engine for a marinized Toyota diesel engine (or similar), how would I get on with shifting gear on my MC1 drive assuming that the shift interrupt will no longer function? Any other "gotcha's" when it comes to swapping...

    Adjusting throttle / shift play

    1982(ish) Mercruiser 228 / MC-1 I've done about eight hours now on my boat since installing a new lower shift cable. There seems to be what I consider an excessive amount of throw required in the throttle lever once the gear in engaged (either forwards or backwards), before the throttle picks...

    Mercruiser R anodes and bonding straps

    Looking through my Mercruiser service manual there is reference to there being a replaceable anode attached on, or under the hydraulic manifold on the gimbal housing. My out drive currently does not have one of these anodes installed and I'm wondering whether the early ones never ad these, and /...

    Unleaded fuel, and fuel additives in a 305

    Ok, here's a question which two mechanics have given me contradicting answers to; I have a 1983 Mercruiser 228 (GM 305) and I am wondering whether or not I should be using some sort of fuel additive with unleaded fuel to guard against such things as valve seat recession, etc? Would this engine...

    Lower gearbox oil leak - Merc 'R'

    Hi Having just got my new-to-me boat up and running after being inactive for over twelve years I have discovered an oil leak from what appears to be from around the prop shaft leading from the lower gear case (Mercruiser R leg). Since getting the boat going a couple of weeks ago I have only...

    Flushing raw-water cooling system while still in water

    Hi Is there some relatively simple way to flush a raw water cooled Mercruiser 228 / R leg while the boat is still on the water? I guess one way would be to perform some level of acrobatics and lean over the back and try and slip on a set of flush muffs and hose but that would be extremely...

    Mercruiser 228 running too cold

    Re: Mercruiser 228 running too cold OK, hopefully I have managed to attach a couple of pics of my thermostat housing. Sorry for the size and quality, but at this stage they are the only photos I have of it, and it will be a couple of weeks before I can take any more. The two hoses which are...

    Mercruiser 228 running too cold

    Hi I have just finished replacing the manifolds and risers on my newly acquired boat which has a 305 small block 228hp Mercruiser. When I bought the boat, the engine had the original 'log style' manifolds with rear exit risers. I was advised to replace these due their age with newer style center...

    Hi all. My apologies if this topic has already been flogged to death but I just couldn't find the info I need in a search. I am about to replace the old style shift cable on my 'R' leg, I have a new style cable but not the new fittings. While reading through the mercruiser manual I note there...

    Sticky varnish removal

    Ive recently bought a boat which was built in 1983, but has been in storage for the past twelve years. It has wooden cabinetry that is coated with some sort of varnish which has gone sticky, especially if any moisture comes in contact with the surface. Is there a way to remove this stickiness?

    Is the special tool relly needed for replacing bellows?

    I'm just about to embark on replacing the bellows on my Mercruiser-R. Can they be installed without too much difficulty without the special insertion tool?

    Reactivating Mercruiser R / 228 following long storage

    Hi I'm new to this list, and Mercruisers in general. I have the opportunity to purchase a boat from a friend of the family's which has a Mercruiser-R / 228 installed. The boat is in New Zealand. The owner was an extremely pedantic owner who treated the boat like his baby, only ever used in fresh...
