Good afternoon.....

just spent $$ on replacement VST's, fuel system parts (pumps, filters etc.) oil, filters, anodes, plugs, tilt switches, separators, water pumps. Now i find out that i apparently have the dreaded rot. I was told they didn't see anything abnormal when they did the water pumps. Now I have milky oil in both engines. Is it worth having the fix done (and oil pumps while I'm in there) and then selling them with receipts to prove the work was legit? Engines have 1050 hours on them. I have a line on 2 new 300's for the 330 express. I don't want to sell a set of POS engines to someone. That's not right, but I don't know if it is worth the expense to fix and then sell and try to recoup some of the $$ or just try to sell them of for parts cheap. what say you ? The knowledgeable crew? I have about 5k wrapped up in them as of now.
thanks
 
Locally (North Shore MA) most dealers are willing to work out some sort of "trade value" for the old engines, especially if you've spent good money with them prior to repowering. I would discuss with the shop/yard that would be doing the repower, but personally, I wouldn't spend more money on obsolete and flawed engines.
 
Isn’t the mid-section repair $3k/motor? After that repair are they worth $8-10k each with 1000+ hours?

Thus, the reason I'm asking. I'm not sure which way would be the wise choice. With all the other work done I would assume they would be fairly reliable and have a substantial amount of life left in them. I would probably keep them but I'm looking for a little more HP and efficiency on a heavy boat like the 330
 
I looked into it out of curiosity back when I bought my boat on the off chance that I'd need to do it myself. Thankfully, both the Grady White dealership that I bought it from as well as the local one said pulled the lower unit, looked up and said it looked great. As mentioned, out of curiosity sake, I looked online at the repair kits, which at the time were running at right around $600 per outboard and the availability of them was pretty limited in 2021. Now it looks like they're up to just over $800 but they appear to be pretty readily available. I also looked at a couple of videos on YouTube for guys that had done the repairs themselves and they look pretty extensive, unless you've done something similar before. My local GW dealership at the time I had them inspect the exhaust on my outboard said it was right around $2k per outboard to do the repairs, if I needed it done on my boat, which I thankfully didn't. If you can do it yourself, or know someone who can help you, and save yourself potentially $5k-$6k+, then that would be the way to go imo. If not, I'd inquire as to how much you might be able to sell your old outboards for, once they've been fixed. If you put $5k-$6k+ into them and they're only worth say $12k total, then that probably wouldn't be a great route to go. If you can get them repaired for that $5k-$6k range and you're able to sell them for $10k+ a piece, then I think that would be the route I'd go. Or as you mentioned, you could likely run them after you repair them and get another 1k+ hours out of them. But if you're already considering repowering, I imagine that's the route you're more likely wanting to go. Sorry to hear, definitely sucks and it's something that's kind of always at the back of my mind as well. Attached is a link for the repair kit. Good luck and let us know what you decide on doing.
