IF somehow Bennington mistakenly built my boat as a special order ESP, I could theoretically increase my HP and be easily within my boats engineered limits, and the only barrier would be if an ecu flash would mechanically lead to damage of some components in my 200 HP Mercury Verado over time (which I am not willing to risk if that is the case). However, my face plate at throttle lists my boat as an ESP hull and a maximum HP listed at a much higher level than 200 HP - the boat is in storage and I’d have to check to know for sure the specific HP listed on the face plate. This set up is the maximum 200 HP on my size s-series SPS hull, so that is what I went with.Īll my paperwork reflects that the boat is what I ordered. I ordered a 2017 S-series SPS with a 200 HP Mercury Verado. order and paperwork discrepancy with my boat that I have never bothered looking into to.

Anyone know the “real” situation with motors, their engineering parts tolerances, ecu flashes, and increasing HP? Aside from insurance and warranty concerns with an ecu flash and increasing HP, I’ve always wondered about this issue mechanically. Mind you, I’ve heard the complete opposite too (usually from those that did an ecu flash), but I’ve never been sure which is accurate. Verado has different parts engineered with higher stress tolerances. For instance, a 200 has some parts specific to the stresses of that HP, and if you increase HP with an ecu flash to say 250-300, then you may damage certain motor components due to stresses its not engineered to handle whereas an actual 250-300 HP Merc.

I’ve heard that some components inside the motor are not the same, and higher HP versions of a motor have certain parts that are more robust for higher stress tolerances. I’ve heard that even though many motors can be ecu flashed to increase HP, that it’s not a good thing to do to the motor. I’m looking for information from those that know motors particularly Mercury Verado’s if possible. Preface: I have very little mechanical knowledge.
