Is changing the 500hp valve springs a do it yourself thing?
Im mechanically inclined, and have changed valve springs on cars, but not a 500hp. is it just a basic, pull the old one, put the new one on and set the rockers, or is it something i should leave for a professional?

I had to remove mine do to the fact I could'nt get no leverage. I guess it would all depend on what type of tool you use. I had customize my tool. Kept bending.
Typically you have to remove the exhaust just to get to the valve covers.

Can be done without removing the exhaust. Need two types of spring compressors. One being the flat bar style which is good for most of the springs and a screw down style for the ones that are nearest the manifolds and risers.
Did my twins that way so I know it will work. Been there done that.
No problems since. Really no problem before that was noticeable, but did find about 7 (if memory serves me correct) springs broken between the 2 engines. All were the inner springs & was lucky enough that no other damage done and all broken parts were contained within the spring.
Good Luck

BajaRunner,
If you have all the tools and parts on hand figure on an engine a day. My change was on a 36 Outlaw as well. Took me about 3 days for the first engine as the boat was 100 miles from home to start with. Did not have all the things that I actually needed and one of those days was more or less a total waste of time. Second engine once I had everything I needed was completed in one day and encluded the first test run on the hose before re launching it some time later.

No you do not. Mine are naturally the Gils and have the tall later model risers which as I see it be more of an obsticle than the shorter version.
Just use a 1/4 inch drive socket on a long extension to reach the eshaust side valve cover retaining nuts being VERY careful to not drop then as they are removed and reinstalled.
You will need a flat bar stlye compressor that will work for most of the springs and a screw type compressor for the springs that can not be done with the flat bar one. One of the wasted days came when the el cheapo bar type I had bent beyond being usefull. Morel of the story is spend more and get a quality tool to start with.
Need to also remove the shifter cable assembly and the carb linkage to get them out of the way.
