225 promax vs 220 laser

[Image 21]

Other than one motor being a 2.4 and the other a 2.5 what is the difference? Another words basic looks are the same on the efi. Can I put a 220 laser efi on a 2.5 ? Shave the heads a little ? Not afraid to get my hands dirty building.

220 laser is 5 petal, 225 promax is 7 petal. ECU is totally different.

220 Laser was rated at powerhead so more like 200 propshaft HP. Most Pro Maxes would put out 240+ hp at propshaft.

Do the promax motors need any type of crazy maintenance. My 260 would need rings every so often to keep fresh. I see lots of the promaxs for sale. Will be looking to purchase in the spring.

Pro Max way cheaper on fuel and oil.

220 laser is prop rated. All post 1984 merc v6s are prop rated.
