@lakelbjhorn - i hate to see what you're in the middle of, but unfortunately it seems you're going to have a lot of company in that department as folks start digging their boats out of storage for the summer (so if you are going to repair, you should probably try to get your hands on a long...
Thanks for your input/advice @F_R . That's the same conclusion I've come to, that there isn't much to be gained by changing my prop. I def have no intent on winning any races in this shoebox of a boat (I rarely even fish where I know there will be much boat traffic at all)...I just wanted to...
@racerone since you said earlier it should be running 30mph with an 11in pitch...I'm guessing since I'm running 12in pitch and its only turning 4200 rpm (supposedly) and 22mph (via GPS), then can I assume that the boat is just too heavily loaded for the prop I have (with no real alternatives to...
@F_R and @racerone - thanks for the reality check. I was apparently looking at the wrong category from when I purchased the replacement prop...this entire thread has been misdirected - I pulled the existing prop off and looked at the part # stamped on it and it turns out its a 10 1/2 x 12 (not...
Yeah it looks like a Michigan Match 9x10 from Tacoma is in my near future. I wanna err on the side of slower rather than faster on the pitch, as its already goes plenty fast enough. Moreso just concerned about over-revving my new engine...
Thanks for all the input everyone! This site is simply...
So I might need to go post this in the prop forum, but I looked at iboats.com and they don't carry any pin drive props that would fit my engine. Looking at Tacoma props, the closest they have is a 9 x 11. Since that would be a smaller diameter prop, does that affect performance compared to the...
Haha @racerone! I def think it's turning less than that...but get this... I recall my parents telling me my grandparents used to go fishing in that boat WITH another couple (apparently people were smaller in the 70s)and they also said they saw him pull a skier on more than one occasion when they...
Well there you go, guess I need to throw my tach in the trash (its literally crap from you know where overseas) and maybe grab a spare 10" prop (not that I want/need to go faster than it does already).
Thankfully I haven't been running it full throttle at cruise since it seems to make a lot...
Wait, wait, wait....before I go blowing up my sweet running motor...I'm beginning to doubt my little wrap on tachometer...How are you guys measuring rpm on these old motors??? When WOT it sounds like its absolutely screaming....so now I'm thinking my tach is lying and the only reason its only...
Annnnnd now I'm questioning everything, since it seems 7" pitch should be way too low for a boat this small...I suppose I could post a video of it running and planing out to see if it sounds/looks normal to you guys...
Sorry don't have a pic handy except on a previous post of mine (Post #3) - https://forums.iboats.com/threads/1964-crosby-28hp-speeditwin-rescue.705093/
Is it possible the boat is just heavy? It is fiberglass, but i did singlehandedly walk it backwards up an uphill driveway all by myself, so i...
Thanks Kbait. I have played with the tilt pin both up and down and ended up moving my trolling motor to the bow (along with the super heavy deep cycle battery) up front put more weight on the front. It does tend to ride pretty tail heavy with just my 200lb self in the back.
With its current set...
