Hello,
I've been a long time reader and am a new poster to this forum. The maxima forums have been a great help over the years... I appreciate your input
Here is my setup: 1400 Spectrum 1989(became bass tracker I think), Fixed Mount Motor Bracket(to lift the motor up 2.5"). I think the Spectrum is rated for 15hp and 700lb capacity(roughly). See quick picture attached.
Here are my questions:
1. I upgraded from a 94' Johnson 15HP(90lbs) 2 stroke to a 15HP(112lb) Yamaha 4 stroke. Is the extra 22lbs too much hanging off 6" from the rear? That yamaha is extremely heavy. I took the boat out and the transom goans and creaks upon acceleration. It did this with the old motor, but not as often or as much. I think I saw the transom flexing some too, but was too attentive to motoring the channels.
2. Should I add diamond plate to the transom to spread out the force?
3. Should I take off the bracket and try to use the Yamaha motor on the transom?
4. Do other people feel the 4 strokes vibrating at idle? My boat has a resonance now and humms as everything inside buzzes. Underway, the engine smooths out and is quiet and awesome. Should I add a rubber or something to help with the vibration?
5. The wood on the transom seems solid, but that is an option to replace.
6. Upgrade the 14' boat to a sea nymph(just throwing it out there) or something stronger? In Tampa Bay there are tons of boats on CL for cheap, so it is an option. I could do a 14' - 15'. I do not care about going super fast. The Sea Nymph looks comparable to my boat, so I just don't know. I just did my trailer axle and hubs, so i want to keep my trailer.
These questions have been building! I will try to post a picture of the transom. Nothing fancy, 1 floor bracket to the transom.
My main concern is taking on water over the transom. To get to the skinny water, i often tango with large boats and their wakes around the boat ramp. That and a transom that is makeing noises does not instill confidence in me.
Thanks,
John
