    BF45: removing oil pan?

    Hi all My first time posting on this forum. I picked up a BLAF / BF45A which I am in the process of swapping power heads. The original motor is getting water into the combustion chamber (previous owner had corrosion on head welded / resurfaced / new head gasket, to no avail), and I just happened...

    BF35 / BF40 Powerhead Interchangable?

    Hello. I have a brand new BF35 powerhead complete with all electrics etc from approximately the late 1990’s. I’have the opportunity to buy a fire damaged but otherwise complete BF40 of age unknown but presumed to be mid-2000’s. I am still waiting for engine plate details to confirm actual age...

    Removing remotes

    Hi guys I thought this would be a straight forward operation, but never the less here I am.... Can someone please tell me how to remove the whole remote assembly of this style of remote? (Photos found on the net). I can't see any obvious way of removing the shift lever which in turn would allow...

    How many hours out of an E Tec?

    Hi I have the opportunity to buy a 2006 250hp Evinrude Etec. It's a one owner / fully serviced (with dealer records) unit and it looks tidy. BUT it's done nearly 1100hrs. I don't want to get myself into something that's going to cost big money to fix in the short term, so what is a consertive...

    SEI drive water pump failure; engine got hot

    SEI 106 drive / Mercruiser 228 / raw water cooled. Yesterday, about three minutes after applying cruise power I happened to notice the temp gauge trending towards the upper limit of the scale and by the time I had bought the boat to a stop it had climbed into the red. This was after I had...

    MC1 to Bravo 2 Conversion

    How far off are the transom holes and cut-out of an MC 1 if I was to remove that and install a Bravo 2 transom assembly in place? Do any of the holes line up? Would the cutout for the MC1 need to be glassed up and then a new cutout made, or is the bolt pattern / cutout of the Bravo wider overall...

    BMW D636 TA with 190 drive

    Hi Can anyone offer any thoughts on the above engine / drive? One is being offered for sale locally and I'm wondering whether it would be a worthwhile conversion for my boat. I'm currently running an old Mercruiser 228 V8 which goes great but is a bit thirsty. I'm not after racing boat like...

    Volvo 280 Prepurchase Inspection and General Opinions

    Hi I'm a current Mercruiser owner, but I'm looking at a 1985-ish vintage boat which has a 350 V8 coupled to a Volvo 280. It's a fresh water boat. I have never owned, or maintained a Volvo before, and I've read some quite positive things on the net about them. Is an older model drive like the 280...

    Onboard Flushing System For Raw Water Cooled Engine

    I've been thinking about rigging up some kind of fitting within the cooling system of my Mercruiser 228 (raw water cooled) / Alpha 1 which will allow me to flush the cooling system while the boat is on the water, and found this on ebay...

    MC1 Trim Rams on Alpha 1 Drive - Problems

    Hi About a year ago I installed a new SEI Alpha 1 style drive in place of my old MC1. I reused the original trim rams but in order to get the external hydraulic lines of the old style rams to clear the cavitation plate I had to rotate the outer cylinder 180 degrees. This caused the flexible...

    MC-1 Trim Ram Leaking - Repair Or Replace?

    One of the power trim rams has developed an oil leak around where the inner shaft exits the outer housing seal. Is it worth messing about with installing a new seal kit in a thirty year old ram or would I be better off investing me a new (pair) of SEI rams? I currently have an SEI106 outdrive...

    Intermediate Shift Shaft

    Is it necessary to install the intermediate shift shaft in the Alpha series drives with the retaining split pin and washer? Once the drive is installed there really isn't any way for the shaft to fall out. The reason I ask is I'm wanting to swap the shafts between my SEI and MC1 drive and if the...

    Rochester Quadrajet filter

    Looking at replacement carb filters on the net I see that there is an option for a filter with a built in check valve to stop the bowl from draining between uses, is this suitable for marine use or will it cause too much restriction at the higher RPM that marine engines run at? My engine does...

    Refinishing oiled teak with a varnish?

    My boat has a lot of teak cabinetry and trim, both interior and exterior, which is looking pretty weathered. It has previously been oiled but I'm wondering whether it would now be possible to somehow re-do it with some sort of varnish (using the very generic term:-) such as these new aliphatic...

    Setting trim tab angle

    I understand that the purpose of the trim tab anode found on most sterndrives and outboards is, along with combatting corrosion, to offset torque generated by the turning prop. This was very evident on my fathers boat when he first bought it; the tab on the Yamaha 140 was set straight and the...

    MC-1 Oil Seal Question

    I've just finished replacing the upper shaft seals and the oil seal on the drive shaft in the upper unit of my old MC-1 as they were leaking oil on the ground when on the boat, and confirmed by pressure test. When I disassembled the upper drive I discovered a surprising and disappointing amount...

    Bell housing O-ring- glue or no glue?

    Should the large rubber O-ring that is inserted into the bell housing for the outdrive to seal up against ( not the water passage O-ring) be installed with bellows adhesive or left dry? If it should be glued, is there an alternative to bellows adhesive that can be used?

    New SEI 106 outdrive; occasional difficulty coming out of gear.

    A few days ago I installed my new SE106 drive, replacing my MC-1. When I assembled the two halves together I found that the intermediate shift shaft could not be aligned exactly straight ahead on the lower shift shaft, ie the "foot" of the brass intermediate shaft was cocked off slightly in the...
