I just got a 1999 1850 tyee with a 135 optimax and have some questions about props. It currently has a 19P aluminum on it and will do 40.5 mph at 5100 at WOT. I think I should be getting more rpm's? I have access to a 19P SS prop for free. What kind of change if any would I notice? I think I need to maybe try and 18P but not sure. Prefer to stay with aluminum to keep cost down. any thoughts?

You have a great motor, get a great prop. A Tempest 19" might be a bit too much, but are common to find used. Your motor and larger boat might be good fit with 17" or 18" tempest. Lots of bow lift, great handling, and a good top end balance. We have a 19" on our 150 with slightly smaller boat but similar style. We tested a bunch.

Honestly an alum prop on that motor would be a shame IMHO. Good luck.

edit - oh yeah, it is not as simple as just "a stainless steel prop" as there are different styles (models) for different applications. what works on a bass boat (i.e. Laser II) will NOT work on your hull style, regardless of pitch.

      As a recovering machinist, I can appreciate that.  If the spec is 0.001 - 0.0015, then clearly the correct measurement is 0.00125, duh…

      I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought. Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...

      Congrats on the motor!  I think you’ll like it.   I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers.  160 degrees is more than I expected to hear.   Curious why you’re opting for a 3 bank charger with a 24V trolling motor.  Unless you don’t feel you be running you big motor enough to keep that battery up as well?

      I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius) says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.

      You're very lucky a troop of Sea Monkey's didn't carry you away.

      Wasn't terrible at a state park beach. Antelope island maybe.  I wouldn't recommend it as a beach destination tho.  Figured I was there, I'm getting in it.

      The water looked and smelled disgusting with hundreds of thousands of birds sh*tting in there.  About as gross as the Salton Sea. When I duck hunted there I didn't even want to touch the water.

      It's kinda gross with the algae in the summer but I got in it anyway.  Wanted to see the increased bouyancy at work.  You can kinda tuck yourself into a ball and you'll just float with your head above water.  When dry off you look diamond encrusted with the salt.

      We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.

      I've been out on the flats. It's like being on a different planet
