I replaced all three bellows on my alpha 1 gen 2, this fall. In addition, I also replaced the trim sender/limit switches and lower shift cable. All went well. I tested it on the water, today and I have a very small leak coming from somewhere. I had a small amount of water in the bilge that...
I finally got around to installing a new Merc water separating fuel filter on my 3.0L between the tank and the fuel pump. While I was at it, I also replaced the filter element in the fuel pump bowl. But, I got to thinking....Is the fuel filter element in the bowl still necessary? It's really...
Hi. I will soon be installing a water separating fuel filter to my 1998 3.0L Mercruiser I/O. There isn't much room anywhere in the engine compartment.
I'd like to install it in this location (see photo) (temporarily tacked up) above the fuel tank. This location is easy to get to and the...
Hi Everyone,
I have a 1998 3.0L with a Merccarb carburetor. I've been chasing an intermittent problem for 2 years.
The engine starts easily, idles fine initially, and runs great at cruising speed.
Occasionally, however, after running at cruising speed for a while (after the engine is good...
Does Mercury/QuickSilver make a gasket set for the removing and re-installing the Alpha 1 Gen II outdrive or do you have to buy the gaskets and o-rings separately?
I know that Sierra has a set of gaskets but I wondered if there was a Mercury gasket set.
I've owned my boat (1998) with an Alpha Gen II drive for about 2 years. For the past 2 years, I've removed the drive and inspected the bellows in the fall (as part of my fall, DIY drive maintenance). Everything looks good to me and there is no signs of water intrusion. The bellows show know...
I'm replacing my fuel line on my mercruiser 3.0L. I'm having trouble disconnecting it at the fuel pump outlet (see photo). The brass flare nut is off but the fuel line will not budge out of there.
There's a black nut below the brass nut. Does that also need to be loosened? I can't tell if...
I'm about to embark on a Merccarb rebuild, soon.
I plan on immersing the disassembled parts (minus the plastic/rubber ones) in Berryman's B-9 carburetor dip.
My question is how long? I've read several threads that recommend immersing for 24 hours. However, the mercruiser manual states in...
I have a 1998 3.0L engine. I've removed the bowl from the fuel pump to replace the fuel filter. The old filter is the ceramic water separating type.
I'm reading that this filter has been superceded to a paper type (35-803897Q1). Is the new paper type still a water separting filter?
Even...
I have a 1998 Mercruiser 3.0L (with a Merccarb carburetor) that idles fine (both in gear and in neutral). It also runs fine at cruising speed above 2100 RPM. But, anywhere in the range of 1200-2100RPM, it'll hesitate and slowly lose RPM (at which point I will have to increase or decrease...
I have a 1998 3.0L Mercruiser sterndrive motor (SER OL016149). I've seen various horsepower ratings specified for this motor (115 HP, 135 HP and 140HP).
I'm just curious about which one I actually have (mainly for boat insurance purposes). Aren't all 3.0Ls since 1998 the same motor with the...
