Default 1980's 70hp mercury power loss - troubleshoot

Thanks in advance for your help.

I am having problems with power loss with the motor when put into gear.

Idles fine, but when put into gear under load it bogs down and loses power. But if you have ear mufflers or test tank it works fine in gear due to it having no stress or load trying to push the boat?

I had it at a shop they thought they fixed it but no same problem. After that they decided not to charge me their time, and not to try again.

Any thoughts on how I should trobleshoot this problem?

thanks
again
