So glad I got it!

My boat has not started easily since I bought it. I was advised by a mechanic friend of mine to get a new IAC valve which I ordered online cheaply, watched a few instructional videos and then replaced the part myself which saved me a lot of money compared to hiring a mechanic. The boat works so well that I am deeply grateful for this detail. I wish it all helped.

Pros
  • Quality construction
Cons
  • Repair
