15 foot Whaler with a 90 Merc

This is a classic 1980 custom 15' Whaler powered by a stock 1999 90 merc 2 stroke turning a 26" pitch Laser2 prop, mounted on 6" hydraulic jack plate. Hydraulic steering keeps this thing under control. 55+ mph!

@saltwaterallday The Bob's plate works well,I've had it for five years and I've only had the up down switch go on me once-just had to resolder it-just seal the switch box with silicone when you first get it and this shouldn't happen.As for performance when planed out, you can feel the boat accelerate when you raise it from 1" to 3".About 5mph extra at full speed.It raises to 6" for putting around in shallow bays etc.The motor is quiet enough for talking, but the wind noise gets pretty loud

@ Saltwaterallday Wow, is it an older boat? We had a 13 that had the old splashwell and I could see how it would be weaker - there was no support for the transom, the splashwell consisted of a wall that went from gunnel to gunnel.

Sounds like a great idea for your rig-the Bob's Machine is great so far on mine. Would you get an older 90?

@saltwaterallday The transom is really strong. There are no stress cracks after 11 years with the 90 and the jackplate. Mind you I don't hammer it out of the hole very often...

I've had this out in the Gulf of Mexico on three different trips, and so far so good for salt water use. I crave a longer boat for sure, there are very few days that I can open it up full throttle without getting pounded!

@TrustworthyMtgGuy Yeah 48 would be nice - good luck with it. My engine is going to need some work soon, it's running rough at high throttle and losing power. They're great motors, at least mine has been flawless since I bought it new in '99.

Thanks! It's top speed is 56 - 57 mph on the gps.

A friend had a montauk 17' with a 90 Evinrude and it was quick, it went over 45 mph. They are rated for higher HP but not by much.

This video explains why I smile every time i see a Boston Whaler. Well the old whalers......

Grew up on one of those, with a 70 hp evinrude. Best rig on Long Isand Sound. 1978-1990

i tow a avon 340 rib with a 20 four stroke honda outboard behind grandbanks eastbay 38. i can tow it at 22 knots at most and if i get caught in rough weather with 6-8 foot waves im fine would a 90 being towed put to much weight on the transom

[saltwaterallday]

is your engine to loud to talk to the person next to you when planed off

[saltwaterallday]

im not sure yet all the ones i have found on craigslist are older and have not been run for a while that are way over priced or i could get a new one for 2000-3000 but thats as much as a hull so im not sure im still looking. you have a bobs machine shop plate how is it

[saltwaterallday]

A guy had a 13 with etec40 at my dock he had a lot of trouble with the hull he had to get 1 inch thick rods through the transom to the other side of the bilge with 2 inch washers to spread out the weight this was in saltwater and so am I I'm interested to put a 90 yamaha with a Jack plAte from bobs machine shop thAt I found online it looks pretty good and a couple other things like boysen reeds and and a new prop

[saltwaterallday]

would having a 90 on a classic 15 in saltwater be to much??

[oreolover345]

hurt more than anything if u hit ground at top speed

[saltwaterallday]

does the weight of the merc effect your transom?? does the jackplat reduce some of it???
