Hello EJO, it was my pleasure to input. I didn't consider the ride height of your trailer v.s. ground clearance to the skeg. Glad to hear Phils trailer suggestion will do the trick for your outboard height adjustment.

I'm sorry to hear that you do not have the convenience of a local prop shop that would be willing to accomodate a lend-lease option for testing. EJO keep this in mind, as you test heights a stainless prop will be needed as it nears the surface. Aluminum props typically do not fair well nor offer the needed performance when turning near the surface either by a raised outboard or by a positive trim setting.

I too considered a 4-blade prop when working through my own "getting on plane" dilemma. I received some "pros and cons" from members here on W/C when I asked for input. If you haven't yet ask for some prop advise, the topic has been discussed at significant lengths so search the site for info then post a thread. 4-Blade props can be a bit tricky and costly to select and in your case where you can't pre-test before purchasing...definitely research. Don't knock a 3-blade prop just yet EJO, I was very surprise with the Power Tech "semi-cleavers" performance.

I'm not quite sure why Phil advised against 3M's 4200, the bulk of boat riggers here in the Miami and FL. Keyes area use 5200 over the less aggressive 4200 for sealing outboard transom bolts. I am aware they are considered to be more adhesive than sealant but from my experience where applicable, the 4200 has remained flexible with little to no yellowing from exposure and with excellent water seal. In the event I should ever need to remove the 4200 I came across a product in aerosol spray form which aids in breaking down the adhesion binders in 3M's and other marine type adhesive sealants with makes removing it almost as simple as pealing it off like masking tape.

Well good luck with the prop selection and motor height project...post when you've had some test time with the Montauk 150...till then.
