Re: Restoring 1986 Sea Nymph SS155 (pics)
Another successful lake trip in the bag.. despite the fact that I left the boat keys at home and had to go back for them! What's sad is that I packed the night before and grabbed everything; keys, plugs, fuses, tools, GPS, etc. When hooking up the boat the safety chains were too short so I had to get my other set. When I did I left the boat keys in the house next to the tool box as I had just removed the hitch lock and the keys were in my hand. :facepalm:
Ok let's talk prop for a sec... First off I finally got the old prop off which was not an easy task. There was about a spool of fishing line wrapped around the prop shaft and the old prop was corroded on pretty solid. After the prop came off tried to slide the other on and it was a no go. So we spent the next 30-45 min scrapping and using PB blaster on the prop shaft splines to ungunkify them. Post cleaning the prop slid right into place.
One thing that I noticed during this was the current aluminum prop was a 12.25" diameter x 15 pitch. The SS prop is a 11.75" diameter x 15 pitch... soo all that changed in this process was the diameter.
Now let me throw some numbers:
Aluminum 3 blade 12.25" x 15 at WOT ~4400-4500 no GPS speed
Power tech stainless 3 blade 11.75" x 15 at WOT ~4300 GPS topped at 29MPH (rough water but was able to get directly behind another boat's wake... at a safe distance of course)
Load was exactly the same both times out: 4 peeps; 1 cooler; 12 gallons gas; 20lb anchor and chain
Let the debate begin!
Although that's not too much info
Oh and on a side note... the idle is a little low; Running 600 in neutral but when in gear it drops to 500ish ... did better this time out but I'm gonna have to tweak it a little
