| I've got a buddy who has a 1998 Mercury 150 EFI that is losing compression (according to the mechanic he brought it to) and has a seal in the lower unit that needs to be replaced. The mechanic told him compression loss issues usually turn into an expensive fix and it's a deal where the motor could go the next time he uses it or it could last a while. The mechanic quoted him around $400 to replace the lower unit seal.
I have a few questions based on this scenario.
1) Anyone have similar experience with that motor losing compression that you would care to relate? Is it difficult to determine the cause when a motor is losing compression?
2) Where would a guy look for good quality used outboard motors other than Craigslist?
3) What are your thoughts on gambling with his current motor and just fixing the lower unit seal?
Thanks in advance for any advice!

| Why did he take it in to the shop ? Was it running rough , not performing well? Need a little more info. What were the compression readings. If one cylinder is way lower than the others its just a matter of time. So a compression check is one of those things you should do before buying a used motor. |

| I can't see it being $400 for a seal in the lower unit at all. But the compression issue is a huge deal, I would believe him! |

| He took it into the shop after noticing the lower unit lube was cloudy. I don't think he was talking about the main lower unit seal that is behind the prop. The way he made it sound was it is something inside the lower unit. I'll ask him how the mechanic knew about the compression readings. Thanks! |
