Re: 1998 DAUNTLESS 15 Re-power

I have run the new Mercury 75 FOURSTROKE engine on the DAUNTLESS 15 for 3.5 hours. The sea state has been too rough for top speed. The highest engine speed so far is 5000-RPM; I think the engine can get to about 5500-RPM. The low engine speed power is good. The 50 to 60-lbs weight increase in the ne...

Re: 1998 DAUNTLESS 15 Re-power

I decided on a Mercury 75 FOURSTROKE [to re-power the 1998 DAUNTLESS 15].

[The DAUNTLESS 15 boat] is at the shop now. I hope to be running [the DAUNTLESS 15 with the Mercury 75 FOURSTROKE in three days]

I will follow up once I form some impressions. Thank you all for the help. Bob

The weight of the [unspecified model] E-TEC is about 325-lbs.

Re: 1998 DAUNTLESS 15 Re-power

1998 DAUNTLESS 15 Re-power

I have owned [a 1998 DAUNTLESS 15] boat since 2001. I live on a canal in southern Florida. [The 1998 DAUNTLESS 15 is powered by] a 1998 Mercury 75-HP two-stroke-power-cycle engine that weighs about 300-lbs. I may re-power with a Mercury 75 FOURSTROKE or a SUZUKI DF70, and both weight about 350-lbs. ...
