Diesel Re power 1984 26'0" mack

[Anonymous]

I am in the process of a diesel repower does anyone now what size shaft should be installed and prop size, I choose a volvo D4-210 due to price transmission is 1.51 to 1 .

Hmm....My cummins 210 powered Mack runs a 1 1/4" shaft and 16x17 prop w/ 1:1 trans. The prop is a bit too much, yet stock.

With the Volvo and 1.5:1, You'd be better off comparing to a Yanmar powered machine. The torque curve and rpm range are too different.

26' cuddy 210 hp cummins 15x16 prop 1 to 1 , 1018 Warner tranny 1&1/4 shaft. Prop seems right I top out @ 2800 & cruise 22 to 2400.

The engine with transmission, dual controls was $15,152.00 plus $1,348.00 for accessories not including tax. Purchased at Helmut's Marine in San Rafeal, Ca. This is last year 2005 model which is no longer made. Installation was easy. I went ahead and changed the prop shaft to 11/2". Relocated the fuel tank to the center of the craft just forward of the engine. Used the original tank space for the batteries. This allowed 150 Gallons of fuel and a single tank. Pictures will be available within two weeks. Costs are as follows : Tramson Repair for single exhaust in lieu of dual $2,5000.00 included gel coat for entire tramsom. Fuel tank was $700.00 in 1/4" marine grade aluminum welding and breaks performed by myself at our shop. Fuel filtering system with polishing pump and accessories $485.00 material only. New batteries with switch $250.00 material only. Shaft and Prop $1,980.00 including labor at Wilmington Prop in Ca. Total cost so far is $22,415.00 ... when all is said and done $24,000.00 which will include wiring and new pumps.

Jim,

Please post response once you have given her sea trials. Wondering how she is going to handle in a following sea with an additional 1000+ pounds in front of the engine and a lighter stern. (Curious if this will make her more likely to broach assuming the bow will sit deaper.) I'm just before repowering myself and the tanks are out. You have me thinking!

Just for clarity...if it's an '84...it isn't a Mack...but a Hardtop.

What drove the change of location for fuel? 100 gallons of diesel goes a long ways on that size boat/engine.
