I have a 98 mariner jet outboard on my fishing boat. Id like to have alittle more hp. I found a great priced 98 merc 90 hp prop motor but the river I fish in calls for a jet. Will it fit the 90 merc or is it too small?

No it won't fit, but we only know that the year is '78 at least that's what I got out of it, since they don't make 78 HP motor.

If you meant 75HP, then some years would fit, from about 1987 to 2005 will work

The HP is the same, but the lower units are very different.
