I will give an update after my sea trial. I am however making slow progress on freeing up my steering. Any thoughts? It’s all original to...

    Ok everyone. your thoughts on how it sounds and the amount of water coming out of the motor? Is it cycling enough through the motor? The bottoms of the two water pipes that fit into the water pump and lower unit were buggered up some. I straitened them up as best I could. Water is warm coming...

    Thanks a lot. I’m super excited to get her in the water for a sea trial. Motor is running great now. Compression is perfect. just need to get the lower unit buttoned up and I’ll be on my way. I swore to myself I wouldn’t buy another boat, but I couldn’t resist for $800 bucks. Lol

    Yep that’s why I bought it. I couldn’t believe how well it was kept. I’m hoping the gel coat will come back to its former glory. Looks to have original interior except for the above ground swimming pool liner floor covering. Which I think matches pretty well lol.
