will this replace a 35-802893T from Mercury for optimax engine?

I believe the Mercury filter has a finer element then the Quicksilver version. Both fit. Both work. I've been using the Quicksilver version for years on a 4-stroke Mercury 50 EFI. So far, so good. Hope this helps.

Does this fit my 240hp mercruiser jet boat engine...2004 sugar sand sole?

There pretty standard and my guess is yes but i would cross reference the number with a dealer

Will this fit my 3.7 litre mercruiser alpha one

I do not know, Mine is separate off the tank for an outboard motor that was installed by a dealer. The filter will tell you what size threads match the system, if it fits it will work. Your manual will tell you what size you need or look at your old filter and type in the serial # for the correct match. BTW my filter is on a 90 HP Evinrude outboard.

I have twin 5.7s 2006 350 mpi horizons. Will this filter fit?

I would think so . Here again tons of info on the internet. A lot of the info looks like it's right out of the mercruiser manuals.
