Well after 16+ years... I had my heater leak a little water on this years maiden voyage.

I suppose it just finally rusted out inside and broke? Much like the engine water pump I replaced last spring. (rusted and busted)

I assume this is the norm for these heater cores? They last about 15 years?

I need to go remove the old unit but does anyone have any part # or links to a replacement?

I see heater cores talked about in some posts.. I see something about 100 vs 200? I'm not sure what those stats are referring too?

So if anyone can point to an awesome replacement unit? I will check it out.

Thanks in advance.

Wondering if this link to a heater core would suit my needs?

Here is a link from skidim.

NAPA has a part that is supposed to fit:

Skidim (http://www.skidim.com/products.asp?dept=1020) has replacement heater cores. Price on their 200-series seems comparable to the one you found on Summit. Support a MC parts dealer! Plus, they'll probably be able to offer better tech support, as they should be familiar with the heater in your boat.

I have no problem supporting skidim. ;) I have in the past..

I haven't removed the old unit as of yet so I'm not sure what it looks like?.. Is it safe to say that the 1997 PS190 has a 100 series or 200 series? Is that a speed rating? single vs dual speed?

I'm reading that the 200 series from Skidim won't replace a 100 series?

It also looks like I may be able just to replace the core? Which should keep the costs down...

Thanks in advance for any input..

I have a 96 prostar with a heater and po had the same issue. I pulled it last fall. I think it is a 100 series because it has a blower motor inside the box. I removed it, drilled the rivets and pulled the core. I tried to find a replacement but nothing was an obvious drop in. I found a local shop here in town. They ordered a new core and put the old tanks or top and bottom back on so it was a direct replacement. It cost 100 total, was cheaper than replacing it with a new unit, plus I pumped in a few bucks at a local shop. That is the only radiator shop in town. Truly the little guy. I hope these shops can stay in business because once they close, it is almost impossible for someone to open that type of business back up again in this world of regulations.

Thanks for the info Jake.... It looks like I may have a few options. ??

But I still some questions.. Assuming I have a 100 series like you did Jake, I don't see on skidim a replacement for the 100 series? So far it looks like I may only be able to replace/repair the core?

I really would prefer to just buy an complete new unit and install it.

I don't know how your heater is oriented, but on my '96 205 the vents come out of the end of the heater. I don't think vents out of the side would fit due to my kick panel being in the way.

That looks like the one on my 205, but I wound up picking up a nearly matching core from the local auto parts store. I did have to cut out some of the frame to accommodate differences in the vents/hose fittings.

I could not find a matching core online, so I just took the old one into the store and the owner found a pretty good match.

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.
