ContinuousWave: Whaler Repairs/Mods
posted 01-28-2002 11:56 AM ET (US)
I have read all the previous postings on jackplates and have read the websites for suppliers and screamandfly, but still need advice. I have a 1962 short transom 13' Whaler and a 40hp Honda 20" four stroke. Is setback with this size boat and motor advisable or not? Is the Springfield Marine unit with 6" of setback advisable, or is the use of CMC vertical extensions, with little setback a better alternative, given weight of the motor and lever arm of the setback on the transom? Would particularly like lhg's advice, since he seems to have a lot of knowledge, albeit with a larger Whaler. Thanks for help.

Mr. Clark Roberts has the experience your after. If you did read through the post from the last 2 years this would have been evident.
Mr. LHG has experience though limited in comparision.
With the added weight of the 4 stroke you would be wise to use the static extension bracket with next to nothing of set back.
I would hate to see your transom ripped off.

Unless that baby is bristol mint condition...I would stear clear of that weight, setback, torque, & stress on a 40 year old hull.

I cracked my transom with a longshaft omc 25 hp and a jackplate. I would think that the honda is way to much weight and stress for that boat

Well I guess I'd better stay out of this one.
But there is a picture of my 1958 13' Whaler with a four cylinder Merc 50 (about 250#) on it, in the 13' Reference section, testimonials.

I am thinking of adding a tilt/trim with a Honda 40 4 stroke which will put the engine 6" further back ie. a jack plate. According to BW they "can't rceommend it because they have not tested such a set-up". According to CMC on the phone they said it would be ok.
Since the 200+ lbs of the engine already has settled the stern lower than normal with a 35 hp Evie.I'm still hesitant to add the T/T at 6". Would like to hear more experiences.

Like I stated above, she better be mint, I assume yours is Larry. If that transom is just a tad soft, this will be the demise of what could have been another 30years running with a 30hp.

hello, just happened onto this site while surfing. i own a 1970 whaler and have used a cook mgf co. tilt and trim since about 1989 or 1990. i had a 1976 mercury (i think about 274lbs.) mounted on a model pt130 and was very happy with it. the salt water finally got to it last year and i replaced it with a new one. unfortunately i blew my engine the first time in the water with it in june. never seemed to have a problem with the transom.
