I have a 96 mercury 40hp I ran low on oil and it locks up when it warms up. It seems to run ok and the water pump works, I took off the lower unit suspecting a bearing problem but saw nothing obvious and now am thinking it's a bearing in the powerhead and am getting ready to remove and disassemble that. Have been looking on-line in different forums but haven't run across a similar problem. Any input would be appreciated. Thanks.
