Likely a fairly controversial topic, but curious to what the group consensus is...
I am repowering my 1998 191 Mako Center Console.
The hull is 19'-4" and had a beam of 8'-2".
According to Mako Specifications, the Recommended HP for this hull is 150hp.
According to the USCG Placard, the Maximum HP is 180hp.
However, according to the Code of Federal Regulations, Title 33, Section 183.53, I can calculate the Maximum Horsepower Capacity by using the following formula:
Maximum Horsepower = (Boat Length x Transom Width) x 2 - 90.
Using that formula, it gives me a Maximum Horsepower over 200.
Given that this hull was produced prior to 4-stroke technology, I am only considering 2-strokes for weight consideration.
I am looking for better performance than a 150hp, and given the affixed USCG Placard rating of 180hp, a 175hp 2-stroke would have been ideal.
However, 175hp 2-strokes are a needle in a haystack, per my searches.
Comparing weight, a 2003 Mercury 150XL EFI and a 2003 Mercury 200XL EFI have the same weight of 433lbs.
I understand a lot of engineering went into the design of the hull, but am I opening up a can of worms by rigging a 200hp outboard? Id rather cruise at 3500rpms with a 200, than say 4000rpms with a 150. Not really looking to run around the whole day at WOT, but it's nice to have the power, should I need it.
Also, should the USCG inspect my boat, can I reference the Code of Federal Regulations showing that I am still in conformance?
