Heater Core leak on 1997 PS 190

That looks like my 100 series too. There were some cores in a generic parts book at my local parts store too, but I did not find it exactly so I went the repair route. Sounds like you have a few options. I think that if you had to buy a new unit from skidim, you would have to get the entire new unit complete with blower motor and that was expensive.
