hello everyone

im looking into getting a small lake boat thru an acquaintance and i have very little information on it so far so im trying to do the proper homework before i buy, and the more i ask about it the more the price goes up lol.

could anyone please help me identify this motor shown here? i have a feeling its a 90's johnson/evinrude and from what i was told its supposed to be a 25hp, "with a bad water pump" . id like to find out more before i go see it, to be able to negotiate properly having a better idea of repair costs etc

i appreciate the info in advance, i do understand its not the best of pictures =\

best regards

the issue with motors with "bad water pumps" is that often they were over-heated badly. get a compression reading and look at the paint on a power head

for an outboard water pump, if you do the work yourself, your looking at ~$50-$70 for parts and incidentals

if you must pay a marine mechanic to repair, it may take 3 hours (most dont), so add $120 an hour to that and multiply the parts by 2

What we really need to positively identify it are the details from the ID plate which if it is a Johnson or Evinrude will be on the port-side transom clamp bracket. In particular the model number.

One clue that the engine has gotten Hot, perhaps in more ways than one, is that the Core type Plug on the Block with the Serial # is missing or has been poorly seated

I'm always suspicious when a simple repair like a new battery or water pump prevents the seller from demonstrating it. You would think a $50 investment would add a lot more than that to the price...

If it overheated really bad it is a " parts only " motor.----You would be shocked at what it costs to repair that at a shop.

If he’s raising the price when you’re asking questions about it, I’d walk away. Simple repair, tell him to replace water pump and show you it runs and has good compression. Tell him you’ll pay for parts after everything is proven.

i very humbly thank you guys for the info and advice! i will try to make a compression test part of the deal, and as soon as i find more info ill update here =] would it be a mistake to offer 500$ and take everything as-is?

Another test is to take a garden hose and put a couple of inches of water in the boat. Leaks in a riveted boat are a pain to fix.
