cleaning carbs - buy the full kit or just gaskets?

[qbantek]

Hello All,

I recently bought a 1998 Sea Pro 255CC with twin 2004 200HP Mercury outboards and as a precaution I am assuming that I need to do all regular maintenance and replace all parts that should have been replaced within the last 12 months or so.

So far I have done:

- replaced impeller, o-rings and changed oil on the lower units.
- replaced spark plugs on both engines
- replaced in-line fuel filters
- replaced thermostats
- i just finished cleaning the carburetor and replacing all gaskets and parts on the kit for one outboard.

Question:

For this engine I bought 3 REPAIR KIT, Carburetor (811691 3) that comes with a lot of small parts, but a friend told me that I could get away w/ just buying 3 GASKET SET, Carburetor (810749 3) which is a considerably cheaper but includes only gaskets. According to him the rest of the parts should only be replaced if need arises.
In your opinion, is that correct?

Question 2:
Considering all the maintenance I have done so far (I still have outstanding to replace the fuel filter water separators), is there any other maintenance/part replacing that you'll advice me to do?

Thanks!
