96-97 I think was the transition year. They ditched the VST tank and lift pump, and went to the cool fuel system. I think that is also when the serp belt was used.
Here is a manual for the 98. http://www.mercruiserparts.com/selec....asp?type_id=8

1997 was the transition year for the cool fuel system and I believe 1998 was the transition year for the serpentine belt system. I have a 1997 with the cool fuel system and v-belts.

My 97 had the cool fuel system but no serp belt.
Here's the '98 right here...

Check to see if your serial is in that range.
Oh, and don't assume that if your hull is a '98 that your motor is too.

98 is an odd ball year. It is the rear they transitioned from V-belt to serpentine and from a Mefi 1 to Mefi 3. Some engines had a V belt and Mefi 1, some had Mefi 3. The same with the serpentine, some had a 1 and some a 3. The only way to tell is by serial #.
If you are looking to supercharge it and you have a Mefi 1, than plan on replacing it with a Mefi 4 ecm and harness. If you have a 3, then you are good to go. The Mefi 1 has no way to tune in boost. All of the tuning is basically done with fuel pressure and injector pulse width.
