I recently opened up my '79 with 2 people in there and one speedo said 45 and the other said 50--They are kind of old speedos so I don't know exactly how accurate they are. She can still move!!

opened my 82 up Sunday and it said 42 with 4 people in it -- good enough for me

so if mine is only going around 37 or so, give or take (w/ 3 people) should I be concerned? What could improve this?

Several things to consider - is your hull clean, is the air filter clean, what kind of prop do you have on it and the list goes on...

I bought the boat in the beginning of the month, I haven't started breaking down the oxidation on the hull yet but have gotten all the supplys, I don't know what kind of prop is on it, but it has been replaced. Do I need to replace the air filter or just clean it. Any suggestions? :huh:

It shouldn't have an air filter on it but a spark arrestor instead. Never hurts to replace on of those if they are dirty. That can affect performance quite a bit. You can get one for a reasonable price here www.skidim.com

GPS it. My 87' will GPS at 43mph. I GPS my speedos everytime we go out. It is standard equipment in my boat. :twocents:


My speedos showed 30mph last night when we unloaded, but the GPS showed 34mph. I have to adjust mine almost everytime.
