Hi guys! I need some advise here. I have a 2007 Evinrude 150 hp outboard motor. The previous owner hit something and damaged the lower unit so I purchased the boat/motor without the lower unit. There doesn't seem to be any damage to the mid-section where the lower unit bolts onto the mid-unit. There is no upper drive shaft and the engine hasn't been started in over a year. I'm wanting to at least do a compression test and then I'll inspect all I can on the power section and mid-shaft before forking out $ for a new lower unit, water pump, propeller, upper drive shaft, etc. I may still rebuilt the upper two sections if needed, but I'll consider finding a rebuilt motor instead should the power section have issues.
Just to verify, are there any reasons why I couldn't do a compression test without the lower unit? You don't need a tranny in order to do a compression test with a car engine, but I'm new to boat motors and I've heard that they're much more complex. I've purchased the official motor repair manual so I should be good to go as far as taking things apart, cleaning, replacing seals, gaskets, etc. I expect to have to purchase a few specialty tool (oh darn), but I have a lot of tools already.
After the motor is checked and good to go, I'll be doing a complete restore of the deck boat. I'll be repainting, reupholstering, upgrading the sound system, etc. I look forward to a new project and plan on making a video of the entire project. I'm sure I'll be bugging y'all over the next few months, but I'll share as I go. My last project was an Acura TL restoration for my son. We did it together and it was a lot of fun...and frustration. My kids and I are now going to tackle the boat restoration. I'll see how long they stay excited and motivated.
Thanks in advance for your help!!
