Awesome , thank you

Finally an update on our prop choice. Bryan at valley prop in Ventura CA recommended a power tech four blade 15 1/4 x 14. Sea trail gave us a comfortable cruise at 3800 rpm , 23 knots and a fuel burn of 1.5 mpg. 4100 rpm , 26 knots 1.3-1.4 mpg. Max rpm is 5700 rpm in calm conditions. Almost thru...

Thank you everyone for your help. I sent an email to Ken at prop god and waiting for a reply but also have a local prop shop that I’m working with and we will be going with a 15 x 15 stainless. They are actually taking by original props that are 15 1/2 x17 and are reducing the diameter by 1/2”...

The mounting is the same and a 25” shaft. But after doing some research it seems the gear ratio is different in the lower unit and a reduction in pitch maybe the answer. Found the others switch from a 3.3 to a 4.2 had similar issues and going with a 15 pitch from a 17 worked. Ekea seems you hit...

I’m less concerned about speed and more concerned about lugging the engines. I just don’t understand how a pair of 3.3 F225’s on the same boat with same props spin at 5500 and then put on a pair of 4.2 F250’s , same boat same props and less load only spin 46-4800. Doesn’t make sense to me.

We have a 2000 marlin with twin 03 F225’s spinning a 15 1/2 x 17 power tech prop’s. WOT 55-5600 rpm’s. Corrosion I believe go best of the starboard motor. Decided to repower with new 4.2 F250’s running the same props with the same load we are getting 46-4800 rpm’s WOT. The motors an almost 45lbs...

If you want your anchor to hold, a proper amount of chain is required in order to maintain a horizontal pull on your chosen anchor. With an inadequate amount of chain and some swell you’re likely to create a more vertical pull on the anchor and possibly dislodging it. Take a glance at a...

Are the motors still available ?

Be sure to check behind the thermostat in the cooling water passage way on all Yamaha outboards especially the F-150’s and F-225’s were I have experienced severe corrosion due to dissimilar metals from the thermostat and cast aluminum water way sitting in salt water. Not a warm water thing ...

Glad you found a replacement , found mine at grainger.

If clement falls thru please let me know. Matt (310)753-2528. Thanks

We have a 2000 Grady marlin w/o a gen set , powered by a pair of F-225 Yamahas. Currently have stainless three blade props , not exactly sure of diameter but seem to be 15 or 15 1/4 x 17. Boat seems to do well , just wondering if anyone was using some thing different along with some numbers...
